The sun is a celestial body that provides light for the Overworld.


Main article: Daylight cycle

The sun and moon rise in the east and set in the west.

When the player creates a new world, the time is set to dawn and the sun starts on the horizon. As time passes, it slowly moves across the sky. As the sun sets, the moon rises. Overall, daytime lasts 10 minutes (in real-time).


Sunlight refers to the light, particularly sky light, which illuminates all blocks directly below the sky, and which do not have a shadow cast over them by an opaque block or by inclement weather. Clouds themselves do not cast shadows; however, during inclement weather (rain and snow), the sky darkens and reduces the amount of sunlight in the world. During these storms, the ambient light value during the day is reduced to 12 from the usual 15, and in thunderstorms the light level is reduced to 10 although treated as 5, allowing hostile mobs to spawn.

When the sun rises and sets, blocks exposed to sunlight change their light level depending on the angle of the sun, giving the effect of gradually getting lighter at dawn and gradually getting darker at dusk. However, shadows of blocks are not affected by the position of the sun in the sky, making sundials impossible.

Illumination decreases with depth underground until ultimately there is no illumination all. A gap or a vertical shaft in the ceiling of a cavern allows sunlight to filter in.

Sunlight can be used to turn dirt blocks into grass blocks, as long as there is an illuminated grass block adjacent to the dirt. Grass blocks spread quickest when exposed to sunlight at the high-point of the day (time 6000).

Effects on mobs[]

Sunlight affects how certain mobsspawn.

Except for bats, which require light level 4 or lower to spawn, passive mobs require a minimum light level of 9 (in Java Edition) or 12 (mooshrooms, polar bears, and rabbits in Bedrock Edition) or 7 (all other land animals in Bedrock Edition) to spawn; therefore, they do not spawn at night.

Hostile mobs, in contrast, do not spawn in direct sunlight at light level 7‌[JE only][verify] or 8‌[BE only] or above. Skeletons, zombies, zombie villagers, strays, drowned and phantoms are set on fire for 160 ticks upon entering an area fully illuminated by sunlight, and they try to avoid such areas. They do not burn while in water, in the rain, wearing a helmet, or in the shade. Spiders become neutral while in direct sunlight, until attacked by the player. Endermen teleport away from players in sunlight. All other hostile mobs, such as creepers, slimes, and silverfish, are completely unaffected by sunlight.

Boss mobs do not take damage from sunlight; they spawn regardless of the light level.

Issues relating to "Sun" are maintained on the bug tracker. Report issues there.


  • The sun is visibly larger during sunrise and sunset.
  • If the player is underwater or underground and looks at the sun, it appears the same as the sun at sunset. This is due to the way the sun is rendered when exposed to the sky.
  • Standing or flying at a height above the terrain of approximately 1.4× the render distance, the sun appears opposite to the moon in the sky, making it seem almost as if the player is in space.


  • Example sunset seen from the top of a jungletree.

  • The sun viewed from high up, making it seem like the player is in space.

  • In Bedrock Edition, when looking toward the sun. The sky gets slightly darker and the sun slightly larger. (You may need to click the image to see it better.)

Why Panama is the only place in the world where you can see the sun rise on the Pacific and set on the Atlantic?

Because Panama makes an S-curve there and runs southwest to northeast, it’s possible to watch the sun rise from the Pacific side and set in the Atlantic. In fact, ships actually transit the Panama Canal east to west if they’re on a voyage west to east, and vice versa.

Does the sunrise sun rises in the west the west?

The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that’s because Earth spins — toward the east.

Does the Bible say the sun will rising in the west?

No. The Bible often references where the sun rises as as a poetic description of east, and where the sun sets as a poetic description of west. A search of over two dozen electronic Bibles turned up no such language. The closest was “when a cloud rises in the west….”

Does the moon ever rise in the west?

The moon rises in the east and sets in the west, each and every day.

Why is the moon on the wrong side?

Some people think a moon visible in the west after sunset is a rising moon. It’s not; it’s a setting moon. As Earth spins under the sky, all sky objects rise in the east and set in the west. Such a moon lies not opposite the sun, but, on the contrary, on nearly the same line of sight to the sun, as seen from Earth.

Where does moon rise first?


Where does the moon get its light?

Unlike a lamp or our sun, the moon doesn’t produce its own light. Moonlight is actually sunlight that shines on the moon and bounces off. The light reflects off old volcanoes, craters, and lava flows on the moon’s surface.

Can we survive without the moon?

It is the pull of the Moon’s gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth’s tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).

Is Moon a natural source of light?

Moon doesn’t have its own light and it either reflects or refracts the light of the sun. Hence it can be said that the moon is not the natural source of light. Therefore, the statement ‘the moon is a natural source of light’ is false.

Is Moon artificial source of light?

The Moon is not a light source, it does not make its own light. The Moon reflects light from the Sun. We can see the Moon because light from the Sun bounces off it back to the Earth.

Is Moon a artificial satellite?

The moon is a satellite because it moves around Earth. Earth and the moon are called “natural” satellites. But usually when someone says “satellite,” they are talking about a “man-made” satellite. Man-made satellites are machines made by people.

Is the main source of light on Earth?

Light is produced by the sun. The sun is the main source of heat, warmth, and light for organisms living on Earth.

Is Fire artificial or natural light?

Fire has long been the only source of artificial light and today still, a large portion of the world’s population uses fire as their primary light source. Humans discovered fire early on in their history and used burning or heated materials as light sources.

What is the bouncing of light called?

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection.

Which is the main source of water?

The main sources of water are surface water, groundwater and rainwater.


Where the sun rises

Surely many times you have wanted to orient yourself and have looked where the sun rises. Since childhood you have always been told that the Sun rises in the east and sets in the west. Also, there have always been some signs of it in western movies. This typical orange sunset with the huge Sun falling over the horizon line is characteristic of the sunset. However, the sunrise and sunset vary greatly depending on where you are. Where does the Sun really rise?

In this post we are going to tell you everything you need to know about it and you will be able to teach yourself to position yourself much better by guiding you from our biggest star. Do you want to know more about the subject? Read on to find out hsbc bank usa phone number of Contents

The Sun in ancient civilizations

Our great star of the Solar system it is fixed in the Universe. However, from a terrestrial point of view, it is he who seems to move since, throughout the day, it changes its position. The movement of an object occurs with respect to an observer. For this reason, since ancient civilizations it was thought that it was the Sun that moved and not the Earth.

There are numerous civilizations that, since ancient times, have granted a special cult to the elements of nature. In most of them, the Sun was the most acclaimed element of all, as it was the one that illuminated our lands and gave light to the crops. The study of their movements has served to create ancient clocks in which the tiny homes for sale in raleigh nc were based on the position of the Sun in the sky at the end of the day.

This is how the position of the Sun and the behavior of the days were investigated. Nowadays, we know that the number of hours of daylight that we have varies between the seasons. This is due to the movements of rotation, translation and nutation of the Earth. In addition, what really affects us to heat and cold is sun rises in the west inclination with which the sun's rays strike the Earth's surface and not the distance between the Earth and the star.

This has always had scientists restless, until later it was discovered that it was the Earth that was moving and not the Sun. However, where does the Sun rise and where does it set? Depending on the position of the observer, can it change or is it an infallible option to guide and orient us?

Cardinal points

Darkness has always been related to evil and negative behavior. This is why the Sun has been studied since ancient civilizations. They have always wondered where the Sun rises. However, although it seems logical, it is not.

This is where the function comes in the Cardinal points. It is a reference system that helps us guide ourselves on a map and know how to orient ourselves at all times. These cardinal points have been standardized internationally, so that they are the same for everyone. These world-standardized cardinal points are: North, South, East and West.

Theoretically, the sun rises in the East and sets in the West. We have heard this say millions of times from millions of people. If we are lost in the middle of a field, surely someone will have said "the Sun rises in the East and sets in the West." However, it is not so easy to know, since there are some inconsistencies that will make us doubt this statement.

Where does the sun really rise

You have to know that the Sun rises in the East as it is always said, but it only does so twice a year. This is because the inclination of the Earth and its rotational and translational movements make the cardinal points from which the Sun rises they are not always in the same place.

When saying that it is placed in the West, it will happen in the same way as with the East. It only comes out twice a year. This has to do with what we have mentioned above about the length of days throughout the seasons of the year. Depending on the inclination with which the sun's rays reach the earth's surface and the translational movement that the Earth has at a certain moment of its orbit, the Sun will rise closer to the cardinal point East or not. It only does it exactly twice a year, during the spring and fall equinoxes.

These are the moments in which the Earth is aligned in such a way with the Sun that its rays can perfectly go out in the East and set in the West.

The importance of the equinoxes and solstices

In order to know the sunrise and sunset, the equinoxes and solstices are very important elements. During abs and booty workout at home spring and fall equinoxes are the only two moments in which the sun's rays reach us as perpendicular as possible to the earth's surface. On the other hand, during the solstices, we can see that we have the rays more inclined than ever.

These factors are taken into account to know the number of hours of sunshine that we will have throughout a day and at the end of the seasons. For this reason, it is important to fix the cardinal points and to know well the position of the Earth with respect to the Sun in its orbit of translation to know exactly where the Sun will rise.

During the rest of the year other than the equinoxes, the Sun rises somewhat further north in spring and summer, while in the months colder fall and winter will come out a little more south-facing.

As you can see, not everything is black and white in this astronomy thing. Neither can it be correctly stated that the Sun rises in the East nor that it sets in the West. So, to guide us through the field, we can use other types of signs that are more reliable or wait until the times are very close to the equinoxes.


Do the Sun and Moon Really Rise in the East?

Astronomy is the most ancient scientific discipline known. Such long-standing acquaintance, however, sometimes leaves us feeling that celestial phenomena are trivial. Is there anything simpler than knowing that the Sun rises in the east and sets in the west? After all, it happens every day of our life, right?

Well, not really!

When does the Sun not rise in the east and set in the west?

The Sun rises due exactly east and sets due exactly west on only two days of every year.

Sunrises and sunsets happen because Earth spins, counter-clockwise if we look down at the North Pole. The Sun rises and sets exactly due east and west only when the circular path of our turn on Earth’s surface splits into two equal parts, half in the light and half in the dark. As our planet’s rotation axis tilts by 23.5° with respect to its orbital plane, this alignment happens only at the spring and fall equinoxes.

Earth's tilt and orbit

During an equinox, the plane separating Earth’s day and night sides contains both the North and South Poles. On any days other than the equinoxes, this plane is askew, and our circular path of rotation passes unequally through Earth’s lit and dark sides. Therefore, the lengths of night and day vary, as does the position of the Sun’s rise and set on the horizon.


What about the Moon?

We have seen that changes in the positions of sunrises and sunsets occur because our planet’s rotation axis tilts with respect to Earth’s orbital plane, and because that tilt changes boone county gis respect to the Sun as Earth moves in its orbit. We can use the same reasoning to explain a similar phenomenon for the Moon.

The Moon’s orbit around Earth forms an angle of about 5° with respect to Earth’s orbital plane. So Earth’s rotation axis tilts by about 28.5° with respect to the Moon’s orbital plane. So moonrise will also shift north or south of due east as the Moon completes its orbit.

Earth's and Moon's tilts

In this case, though, the changes occur over the period of roughly a month sun rises in the west of a year. Earth must complete a iglesia de san jose obrero en winnetka ca orbit for the Sun to go through its extremes, rising the furthest north of east during summer solstice and the furthest south of east during winter solstice. The same holds for the Moon, which must also complete a full orbit around Earth to go through the extremes of its rising and setting locations.

Why does strata trust company Moon rise later every day?

As both Earth and the Moon are moving in their orbits, moonrise occurs later every day. Just jose gregorio de la rivera espiritismo Earth spins counterclockwise when viewed from the North Pole, the Moon also orbits Earth counterclockwise. Therefore, every time we spin 360° with respect to the stars, completing a sidereal day (23 hours and 56 minutes), the Moon has moved a little in its orbit around Earth. The Moon orbits Earth every 27.32 days with respect to the stars, marking a sidereal month, so the amount it moves in one sidereal day is (360/27.32) degrees, about 13°. Earth turns 360° every sidereal day, so it will take about 13*(23.9/360) hours to make up the remaining 13°: 52 minutes. Each moonrise, then, will occur roughly 52 minutes later than the one before it.

Because the phase of the Moon also depends on its position relative to Earth and the Sun, the phase will change along with the time that the Moon rises and sets. Read more about the hows and whys of the phases of the Moon here.

Venus: The hot, hellish & volcanic planet

Venus, the second planet from the sun, is named after the Roman goddess of love and beauty and is the only planet named after a female. Venus may have been named after the most beautiful deity of the pantheon because it shone the brightest among the five planets known to ancient astronomers.

In ancient times, Venus was often thought to be two different stars, the evening star and the morning star — that is, the ones that sun rises in the west appeared at sunset and sunrise. In Latin, they were respectively known as Vesper and Lucifer. In Christian times, Lucifer, or "light-bringer," became known as the name of Satan before his fall. However, further observations of Venus in the space age show a very hellish environment. This makes Venus a very difficult planet to observe from up close, because spacecraft do not survive long on its surface.

What is Venus like?

Venus and Earth are often called twins because they are similar in size, mass, density, composition and gravity. Venus is actually only a little bit smaller than our home planet, with a mass about 80% of Earth's. 

The interior of Venus is made of a metallic iron core that's roughly 2,400 miles (6,000 km) wide. Venus' molten rocky mantle is roughly 1,200 miles (3,000 km) thick. Venus' crust is mostly basalt, and is estimated to be 6 to 12 miles (10 to 20 km) thick, on average.

Venus is the hottest planet in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth. As a result, temperatures on Venus reach 880 degrees Fahrenheit (471 degrees Celsius), which is more than hot enough to melt lead. Spacecraft shelby county state bank elk horn iowa survived only a few hours after landing on the planet before being destroyed.

With scorching temperatures, Venus also has a hellish atmosphere, that consists mainly of carbon dioxide with clouds of sulfuric acid and only trace amounts of water. Its atmosphere is heavier than that of any other planet, leading to a surface pressure that's over 90 times that of Earth — similar to the pressure that exists 3,300 feet (1,000 meters) deep in the ocean. 

Incredibly, however, is that early in Venus' history, the planet may have actually been habitable, according to models from researchers at NASA's Goddard Institute for Space Studies and other studies. 

Venus' surface is extremely dry. During its evolution, ultraviolet rays from the sun evaporated water quickly, keeping the planet in a prolonged molten state. There is no liquid water on its surface today because the scorching heat created by its ozone-filled atmosphere would cause water to immediately boil away.

Roughly two-thirds of the Venusian surface is covered by flat, smooth plains that are marred by thousands of volcanoes, some of which are still active today, ranging from about 0.5 to 150 miles (0.8 to 240 km) wide, with lava flows carving long, winding canals that are up to more than 3,000 miles (5,000 km) in length.

Six mountainous regions make up about one-third of the Venusian surface. One mountain range, called Maxwell, is about 540 miles (870 km) long and reaches up to some 7 miles (11.3 km) high, making it the highest feature on the planet.

Venus also possesses a number of surface features that are unlike anything on Earth. For example, Venus has coronae, or crowns — ring-like structures that range from roughly 95 to 1,300 miles (155 to 2100 km) wide. Scientists believe these formed when hot material beneath the planet's crust rose up, warping the planet's surface. Venus also has tesserae, or tiles — raised areas in which many ridges and valleys have formed in different directions.

With conditions on Venus that could be described as how do i pay someone with chase quickpay, the ancient name for Venus — Lucifer — seems to fit. However, the name doesn't carry any fiendish connotations; Lucifer means "light-bringer," and when seen from Earth, Venus is brighter than any other planet or even any star in the night sky because of its highly reflective clouds and its closeness to our planet.

What is Venus' orbit like?

Venus takes 243 Earth days to rotate on its axis, which is by far the slowest of any of the major planets. And, because of this sluggish spin, its metal core cannot generate a magnetic field similar to Earth's. The magnetic field of Venus is 0.000015 times that of Earth's magnetic field.

If viewed from above, Venus rotates on its axis in a direction that's the opposite of most planets'. That means on Venus, the sun would appear to rise in the west and set in the east. On Earth, the sun appears to rise in the east and set in the west.

The Venusian year — the time it takes to orbit the sun — is about 225 Earth days long. Normally, that would mean that days on Venus would be longer than years. However, because of Venus' curious retrograde rotation, the time from one sunrise to the next is only about 117 Earth days long. The last time we saw Venus transit in front of the sun was in 2012, and the next time will be in 2117.

Here are some of Venus' orbit parameters, according to NASA:

  • Average distance from the sun: 67,237,910 miles (108,208,930 km). By comparison: 0.723 times that of Earth.
  • Perihelion (closest approach to sun): 66,782,000 miles northwest savings bank online banking km). By comparison: 0.730 times that of Earth.
  • Aphelion (farthest distance from sun): 67,693,000 miles (108,942,000 km). By comparison: 0.716 times that of Earth.

What is Venus' climate like?

The very top layer of Venus' clouds zips around the planet every four Earth days, propelled by hurricane-force winds traveling roughly 224 mph (360 kph). This superrotation of the planet's atmosphere, some 60 times faster than Venus itself rotates, may be one of Venus' biggest mysteries. 

The clouds also carry signs of meteorological events known as gravity waves, caused when winds blow over geological features, causing rises and falls in the layers of air. The winds at the planet's surface are much slower, estimated to be just a few miles per hour.

Unusual stripes in the upper clouds of Venus are dubbed "blue absorbers" or "ultraviolet absorbers" because they strongly absorb light in the blue and ultraviolet wavelengths. These are soaking up a huge amount of energy — nearly half of the total solar energy the planet absorbs. As such, they seem to play a major role in keeping Venus as hellish as it is. Their exact composition remains uncertain; Some scientists suggest it could even be life, although many things would need to be ruled out before that conclusion is accepted.

The Venus Express spacecraft, a European Space Agency mission that operated sun rises in the west 2005 and 2014, found evidence of lightning on the planet, which formed within clouds of sulfuric acid, unlike Earth's lightning, which forms in clouds of water. Venus' lightning is unique in the solar system. The lightning is of particular interest to scientists because it's possible that electrical discharges from lightning could help form the molecules needed to jumpstart life, which is what some scientists believe happened on Earth.

A long-lived cyclone on Venus, first observed in 2006, appears to be in constant flux, with elements constantly breaking apart and reforming.

How have we explored Venus?

The United States, Soviet Union, European Space Agency and Japan Aerospace Exploration Agency have deployed many spacecraft to Venus — more than 20 so far. NASA's Mariner 2 came within 21,600 miles (34,760 km) of Venus in 1962, making it the first planet to be observed by a passing spacecraft. The Soviet Union's Venera 7 was the first spacecraft to land on another planet, having landed on Venus in December 1970. Venera 9 returned the first photographs of the Venusian surface. The first Venusian orbiter, NASA's Magellan, generated maps of 98% of the planet's surface, showing features as small as 330 feet (100 meters) across.

The European Space Agency's Venus Express spent eight years in orbit around Venus with a large variety of instruments and confirmed the presence of lightning there. In August 2014, as the satellite began wrapping up its mission, controllers engaged in a month-long maneuver that plunged the spacecraft into the outer layers of the planet's sun rises in the west. Venus Express survived the daring journey, then moved into a higher orbit, where it spent several months. By December 2014, the spacecraft ran out of propellent metro bank atm card requirements eventually burned up in Venus' atmosphere.

Japan's Akatsuki mission launched to Venus in 2010, but the spacecraft's main engine died during a pivotal orbit-insertion burn, sending the craft hurling into space. Using smaller thrusters, the Japanese team successfully performed a burn to correct the spacecraft's course. A subsequent burn in November 2015 put Akatsuki into orbit around the planet. In 2017, Akatsuki spotted another huge "gravity wave" in Venus' atmosphere. The spacecraft still orbits Venus to this day, studying the planet's weather patterns and searching for active volcanoes.

As of at least late 2019, NASA and the Russian Academy of Sciences' Space Research Institute have discussed collaborating on the Venera-D mission, which would include an orbiter, a lander and perhaps a solar-powered airship.

"We're at the pen-and-paper stage where we're considering what science questions do we want this mission to answer and what components of a mission would best answer those questions," Tracy Gregg, a planetary geologist at the University at Buffalo, told in 2018. "The earliest possible launch date we'd be looking at is 2026, and who knows if we could meet that."

NASA has more recently funded several extremely early-stage mission concepts that could look at Venus in the coming decades, under the NASA Innovative Advanced Concepts Program. This includes a "steampunk" rover that would use old-school levers instead of electronics (which would fry in Venus' atmosphere), and a balloon that would check out Venus from low altitudes. Separately, some NASA researchers have been investigating the possibility of using airships to explore the more temperate regions of Venus' atmosphere.

Most recently, in 2021, NASA announced two new missions to Venus that pnc small business account view launch by 2030.

The agency announced June 2, 2021 that they will be sending missions DAVINCI+ and VERITAS, chosen from a shortlist of four spacecraft, for the next round of Discovery missions to Venus. 

DAVINCI (Deep Atmosphere Venus Investigation of Noble Gases, Chemistry and Imaging) will dive through the planet's atmosphere, studying how it changes over time. VERITAS (Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy) will map the planet's surface from its orbit using radar. 

Is there life on Venus?

While destinations in our solar system like the moons Enceladus or Titan or even planet Mars are currently the go-to spots to search for signs of extraterrestrial life. 

But a breakthrough scientific discovery in 2020 suddenly had scientists discussing whether or not it was possible that life could somehow exist in the present-day hellish atmospheres of Venus. 

Now, scientists think that it is most likely that, billions of years ago, Venus could have been habitable and fairly similar to current-day Earth. But since then, it has undergone a drastic greenhouse effect that has resulted in Venus' current iteration with scorching surface temperatures and an atmosphere that many describe as "hellish." 

However, in 2020, scientists revealed the discovery of a strange chemical in the planet's clouds that some think could be a sign of life: phosphine. 

Phosphine is a chemical compound that has been seen on Earth as well as Jupiter and Saturn.  Scientists think that, on Venus, it could appear as it does on Earth, for very short amounts of time in the planet's atmosphere. 

But what does this phosphine discovery have to do with the search for life? 

Well, while phosphine exists in strange ways like as rat poison, it has also been spotted alongside groups of certain care credit bill pay and some scientists think that, on Earth, the compound is actually produced by microbes as they decay chemically. 

This has caused some to suspect that, if microbes could, in fact, create phosphine, then perhaps microbes might be responsible for the phosphine in Venus' atmosphere. Since the discovery there have been followup analyses that have made some doubt whether or not the compound is created by microbes, but scientists are continuing to investigate, especially with new missions planned for the planet.

Seasonal change

Seasonal variations in where the Sun rises and sets and changes in the length of daylight hours throughout the year are caused by the constant tilt and orientation of the Earth’s axis in relation to the plane of its orbit around the Sun (23.5 degrees from the vertical, the North Pole pointing towards the star Polaris in the constellation Ursa Minor). In June, the northern hemisphere tilts towards the Sun rises in the west. The Sun rises in the northeast, passes at its highest across the sky, and sets in the northwest, spending more than 12 hours above the horizon (about 18 hours in the UK). In places north of the Arctic Circle, the Sun may never set at all. In December, the northern hemisphere tilts away from the Sun. The Sun rise in the southeast, passes at its lowest across the sky, and sets in the southwest, spending less than 12 hours above the horizon (about 6 hours in the UK). In places north of the Arctic Circle, the Sun may never rise at all. In March and September the northern hemisphere tilts neither towards nor away from the Sun. The Sun rise due east and sets due west. Day and night are of equal duration. On any given day of the year shadows are long at sunrise and sunset and short at noon. Shadows are longest overall during months when the Sun remains generally low in the sky. A year is in fact the time taken for the Earth to make one complete orbit citizens bank student loan contact number the Sun. As measured by the time taken for the Sun to show itself at exactly the same spot in the sky again, having moved through the variations and changes described above, a year lasts about 365.25 days. A calendar year (Gregorian) lasts only 365 days. The quarter day lost is made up in a leap year.

In addition to causing variations in where the Sun rise and sets and the length of daylight hours throughout the year, the constant tilt and orientation of the Earth's axis in relation to the plane of its orbit around the Sun also causes the seasons. In the UK, our cycle of seasons includes spring (which begins at the time of the spring equinox sun rises in the west about the 21st of March), summer (which begins at the time of the summer solstice on about the 21st of June), autumn (which begins at the time of the autumnal equinox on about the 22nd of September) and winter (which begins at the time of the winter solstice on about the 21st of December). During warm summer months, the northern hemisphere is tilted towards the Sun and daylight hours are long. As the Sun rise well above the horizon, the amount of solar energy received at the surface of the Earth is concentrated within a small area. As the Earth leans towards it, the Sun's ray hit the Earth's surface at high angles. Not only is the Earth's surface heated for more than 12 hours, the Sun's heating effect is more efficient. During cold winter months, the northern hemisphere is tilted away from the Sun. Daylight hours are short. As the Sun hardly rise much above the horizon at all, the amount of energy received from it is spread out over a large area. As the Earth leans away from it, the Sun's ray hit the Earth's surface at low angles. Not only is the Earth's surface heated for less than 12 hours, the Sun's heating effect is less efficient.

For each of the situations described earlier, the southern hemisphere experiences the exact opposite.

While the mean distance between the Earth and the Sun is 150 million kilometres there are times during its elliptical orbit when it moves closer and times when it moves further away. At perihelion (closest), the Earth comes to within coldwell banker greenwich ct 147 million kilometres of the Sun. At aphelion (furthest), that distance is extended to 152 million kilometres. Interestingly, the northern hemisphere tilts towards the Sun and experiences summer at aphelion and tilts away from the Sun and experiences winter at perihelion.
