Where the sun rises at the equator. As the sun rises and sets. Why is the sun red
The sun is the source of life for our planet. The heavenly luminary caresses us with its warmth, illuminates us during the day and gives joy to everything that exists on Earth. Another important function: orientation assistance. Thanks to the sun, we can determine the cardinal points and choose the right direction.
Sun way
Every morning, the gentle sun calls us to awakening and new discoveries in this wonderful world. And in the evening, it, making its slow move across the sky, goes beyond the horizon, giving you the opportunity to relax after a busy day at work. Where does this journey start? Where does the sun set at the end of the journey?
The ascent of the main luminary begins in the east. The sun leaves us at the end of the day in the west. After that, it continues its journey, but on the other side of our amazing planet. And in the morning it rises again in the east. This is how the described picture appears to us from the Earth. Interestingly, ancient people considered this view to be wrong. In that case, where does the sun actually set, and how does it reappear in the sky?
If you do not delve into the details of the worldview of the inhabitants of antiquity, then we can say that they are right. The fact is that our planet is part of the solar system, where the Sun is motionless and is in the center. The earth moves around it in its orbit and, in addition to such a movement, makes revolutions around its imaginary axis. The planet makes a complete revolution in 24 hours, in other words, in a day. That is why it seems to us that the places where the sun sets and where it returns again in the morning are unchanged.
View from space
If it were possible to look at the solar system far from space (so as to see absolutely all the planets), then the picture would be as follows: all celestial bodies of this system rotate in the same direction from west to east (counterclockwise). In fact - Venus rotates around its axis in the opposite direction to the rotation of other planets. There are astronomers' assumptions that a very powerful asteroid hit it many years ago and violated the direction of rotation with its impact. Uranus, too, under the influence of such forces, seemed to be overturned. Now, watching him, you see a picture of rotation as if from the side.
North Pole and other parts of the world
If a person could study the movement of the main luminary from the direction of the North Pole, then he would see the rotation of the Earth counterclockwise, as well as the place where the sun sets and how it rises. Visually, the movement of a celestial body will appear as a move from east to west. In fact, it will move east, and the Earth will rotate around its axis.
Interestingly, in different parts of the world the sun does not rise at the same time. For example, on the East Coast of the United States, this happens even 3 hours before those areas that are on the West Coast. Accordingly, the sunset in different parts of the world falls at different times.
Twilight
The immediate period of time before sunrise and before sunset is twilight. This is a particularly beautiful sight. The disk of a celestial body is located very close to the horizon, part of the rays enter the upper atmospheric layers and are reflected on the surface of the Earth. The duration of such a colorful spectacle lasts about 2 hours. But this is only in temperate latitudes. In the polar regions, before the sunset occurs, twilight lasts several hours. Directly at the poles, this period takes from 2 to 3 weeks! At the same time, at the equator before sunrise, twilight lasts only 20-25 minutes.
At this time, thanks to the optical effect, we see a stunning picture when the sun's rays illuminate the surface of the Earth and the sky with multi-colored tones.
Orientation: how to determine the cardinal points without a compass on the ground?
If there is a wristwatch with arrows (not electronic), then in the “horizontal” position they need to be turned by the hour hand in the sun. Having drawn an imaginary bisector between the number 12 and the direction to the heavenly body, we get the north-south line. It is also interesting that before noon, the south is to the right of the sun.
Understanding how to determine the cardinal points without a compass, a person will be able to navigate anywhere and go out in the right direction. This knowledge is very important, especially for tourists, forestry workers, hunters, sailors and people engaged in other activities.
The method described above can give relatively correct results in northern latitudes. In temperate it works only partly (especially in winter). In the southern regions, the summer sun is high, so errors may occur. In addition, you need to take into account the transitions to and from daylight saving time (as this affects the definition of noon).
It is also important to remember where the sun rises and where it sets in the middle latitudes. In these places, the main luminary rises in the summer in the northeast, and sets in the northwest. 3moi - in the southeast and southwest, respectively. Only 2 times a year, the sunrise occurs absolutely exactly in the east, and the sunset - in the west. These are the days of the equinoxes - March 21 and September 23.
Shadow and terrain orientation
There is another way to focus on the shadow. In unfamiliar places, when this need arises, you need to take into account different heavenly bodies. At night it can be a polar star, and during the day it can be the sun.
Understanding from which side the sun sets, you can determine other cardinal points and choose the right direction of the path. For example, in the northern latitudes, when the time of summer nights comes, the setting sun is close to the horizon. Therefore, the sky on the north side is lighter than on the south.
It is known that the highest solar position can be determined by the shortest shadow. This corresponds to noon. The direction of such a shadow points to the north. It is the same with the moon: if it is full and occupies the highest position above the horizon, then it is in the south. This is the time when there is enough light to distinguish shadows well. Similarly, with a full moon - the shortest shadow. It's midnight. The direction of the shadow will point north.
And does it rise in the east? Since childhood, we have become accustomed to the fact that the Sun rises in the east in the morning and sets in the west in the evening. But is it really so?
It turns out not really. Indeed, sunrise usually occurs in the eastern side of the sky, and sunset in the western side, but the exact position of the points of sunrise and sunset varies throughout the year and depends on the time of year and the geographical latitude of the place.
You probably know that south-facing rooms are usually very sunny. Why? Because the Sun rises highest above the horizon (culminates, in more scientific terms), being exactly above the southern part of the horizon. That is, on any given day, if the Sun appears above the horizon, it will certainly pass over the south point, and at that moment it will culminate. (Hereinafter, we will only talk about latitudes north of 23.5 degrees, in the tropics everything is a little more complicated). You also, of course, noticed that the length of daylight varies greatly throughout the year: in winter the day is shorter, and in summer it is longer, beyond the Arctic Circle in winter the Sun does not appear from the horizon for some time, and in summer it does not set for several days , or even weeks. Does the Sun move more slowly across the sky in summer than in winter? Of course not!
Exactly at the point of the east, the Sun rises twice a year, on the days of the spring and autumn equinoxes, on the same days it sets exactly in the west, and the length of the day is exactly half a day - twelve hours. After the spring equinox, the day begins to lengthen, and the points of sunrise and sunset shift to the north. (Remember that the Sun must culminate over the south point. If it rises in the northern part of the sky, then, of course, it will take longer than on the equinoxes to get to the south point - this explains the increase in the length of the day.) So lasts until the day of the summer solstice - the Sun rises in the northeast, and sets in the northwest, the points of sunrise and sunset gradually approach each other, and in the subpolar latitudes at some point they merge into one, at the point of the north. After that, the Sun stops setting below the horizon - the polar day begins. On the day of the summer solstice in temperate latitudes, the points of sunrise and sunset are closest to the north point, and the longitude of the day is greatest.
After the summer solstice, the points of sunrise and sunset move back to the points of east and west, the length of the day gradually decreases. After the autumn equinox (on this day the Sun rises in the east and sets in the west), the points of sunrise and sunset again begin to converge, but already in the southern part of the horizon, the length of the day decreases. At those latitudes where there was a polar day for some time in summer, a polar night will come - about the same time as the Sun did not set in summer, it will not appear above the horizon. This will happen when the points of sunrise and sunset merge into one at the point of the south. After the winter solstice, the day begins to lengthen, the points of sunrise and sunset gradually move back to the points of east and west, and everything repeats again.
What happens in the southern hemisphere? In the southern hemisphere, the opposite is true: when we have the longest day, it is the smallest there, when we have the spring equinox, in the southern hemisphere - the autumn equinox. In the southern hemisphere, the Sun culminates over the north point, but rises and sets like ours - in the eastern and western parts of the sky, respectively.
So if you are told that the Sun rises in the east and sets in the west, you can safely answer that this is not true.

Everyone knows that the sun is a star around which the Earth and other planets revolve. Probably everyone has heard that this celestial body appears in the East and disappears in the West. But not everyone knows where the sun sets and why exactly there. Further in the article we will try to consider the question of the place of appearance and disappearance of the heavenly body.
How the sun moves
After the heavenly body has appeared on the horizon, its movement continues uninterruptedly. Throughout the day, you can watch the sun move across the sky. In fact, it is not the sun that is moving, but the globe is revolving around the star. Moreover, the duration of the entire process is 24 hours.
It is easy to explain the fact why a room in an apartment located with windows to the south is always much lighter compared to similar rooms with access to other parts of the world. The thing is that during the day the sun moves along the projection of the south of the horizon and eventually reaches the peak point. This whole process in scientific terminology is called as the culmination of a celestial body.
Everyone knows that the length of the day in winter is significantly different from the summer season. In the hot season, daylight hours seem much longer than in winter. Oddly enough, but to explain the phenomenon is quite easy. The length of daylight is directly dependent on the sun. People who do not know this information may assume that the length of the day is affected by the speed of movement of the heavenly body. But this is an absolute fallacy. In fact, the length of the day depends on the point at which the star rises and sets. It is not difficult to guess that during the calendar year it is always different.
The sun sets in the West only twice a year. These dates are March 20 and 21, and September 22 and 23. They are also called the equinoxes. Just then, the sun sets exactly in the West. The duration of the day is twelve hours. Perhaps these dates are the only ones when the sun really sets in the Western part of the horizon.
After the spring equinox passes, the sun begins to move higher towards the sky, which is why the day begins to become longer. Accordingly, the points of sunset and sunrise are shifting every day closer to the north. This whole process lasts until June 21st. Just on this day, the solstice occurs. It was then that the point of entry is maximally shifted to the north, and the duration of the day is longer.
In cities that are located beyond the Arctic Circle, the points of sunset and sunrise merge into one, which contributes to the fact that the celestial body does not leave the horizon and the polar day comes.
After June 22, the sunset point begins to gradually shift to the western and eastern parts. The same thing happens with the rising point. As a result, the length of the day is shortened. After September 23, the point where the sun rises begins to approach the point of its sunset, this happens south of the horizon. All this lasts until the winter solstice. It was then that the heavenly body appears and disappears to the south of all previous days, and that is why this night is the longest in this period.
An interesting fact is that it is on this day that the polar day is replaced by the polar night. The heavenly body does not appear beyond the horizon. This phenomenon is connected, first of all, with the fact that the points where the Sun sets and where it rises converge in the south. As the winter solstice passes, things gradually begin to change. The points of sunset and sunrise begin to move in the opposite direction, because of this, you can observe the lengthening of daylight hours.
Features of daylight hours in the southern hemisphere
As a rule, in the southern hemisphere of the globe, everything happens the other way around. At the moment when the northern hemisphere has a long day of the year, the opposite one has a short daylight hours. This contrast of phenomena is accompanied by everything. When we have the autumn equinox, then in the southern hemisphere it is spring. The climax of the sun also occurs at the opposite point: at the north. But just like ours the sun sets directly in the western part of the sky.
People have always been interested in the Sun, its location in the sky. There are interesting facts that show how interesting and mysterious this star is.
- As the sun sets, the air temperature gradually drops, and it becomes cold. But it is surprising that at night the temperature does not drop to the maximum value. The coldest period is the morning, just before sunrise.
- All over the globe, people watch the sunset every day. But at the poles, this phenomenon can be observed only once a year.
- In ancient times, people used the sun to determine time. Sometimes the setting of the heavenly body served as a sign of the onset of the time of day. Everything was determined with the help of shadows that were cast by special objects. Thus, the first clocks and even calendars were built.
- With the help of a camera, you can track the path of the sun in a day. To do this, it will be enough to take pictures from one point of the Earth at regular intervals. The same movement can be tracked by days and months.
In conclusion, I would like to note that the sun is a star that gives us warmth and light every day. It is impossible to say exactly where the heavenly body sits. The sunset point shifts every day depending on the season.

The sun is a celestial object that can be seen from anywhere on the planet. The development and preservation of wildlife on earth depends on it, since it is it that gives heat. Every morning it illuminates the sky and many are interested in the question, where does the sun rise?
Where does the sun come from?
The appearance of the sun begins in the east, and gradually moving across the sky, it sets from the opposite side in the west. In ancient times, people considered the Earth to be the center of the universe, and that all heavenly bodies revolve around it. However, this point of view has long ceased to be scientific and has been successfully refuted.
The sun is a star and is motionless, while the earth, moving in its orbit, revolves around it. But, nevertheless, this state of affairs creates the effect that we observe every morning - the sunrise begins in the east and ends in the west.
Why do people need to track the movement of the sun?
With the advent of the need to measure time, people began to look for objects that would help them in this. A long time ago, it was believed that it was possible to find out how much time had passed only by the movement of the sun or moon (at night). Why are people so attracted to this celestial object and why is it so important for some to track its movement?
- Sunrise heralds the beginning of daylight, and its sunset heralds the end.
- The biological clock and rhythms of many living organisms on the planet are guided by it.
- For some, this is important to know when compiling astrological charts and horoscopes.
- These indicators are also used by astronomers for various purposes.
- The change in the position of the sun in the sky allowed the ancient people to create the first timing. For this, they even invented the first stone sundial.
- The calculation of days and months is also based on the position of the sun, including the modern Gregorian calendar. Where the day is measured from one sunrise to the next, and the year is equal to a full circle around the star.
From this it should be concluded that the relevance of tracking the position of the earth relative to the sun does not lose its relevance today. In addition, scientists control its performance, measure activity, predict magnetic storms, etc.
What are the benefits of the sun for humans?
The benefits of the sun in the life of mankind cannot be underestimated. However, scientists continue to investigate its effect on the body. A group of scientists from Edinburgh found that if a person stays in the sun for a while, then the following processes are observed in his body:
- Arterial pressure decreases.
- Reduces the risk of developing thrombosis.
- The body is rejuvenated.
- Improves metabolism.
- Reduces the risk of developing a stroke.
- Improves blood circulation.
In addition, the sun is an excellent prevention of the formation of a heart attack, the development of cancer or other pathologies. In addition, the sun produces such a useful vitamin D for everyone, which strengthens bone tissue and removes heavy metals from the body.
What are the benefits of the sun:
- Promotes the production of serotonin, a hormone responsible for blood clotting. In addition, a sufficient amount of this substance helps to improve mood, which is why it is also called the "hormone of happiness."
- Under the sun, biologically inert NO3 nitrite is released, which helps reduce blood pressure and eliminate the likelihood of developing heart failure or a heart attack.
- The sun's rays have an antibacterial effect, therefore, basking in the sun, wounds and scratches heal faster, acne and pimples disappear.
But this is certainly not the whole list of useful properties that the sun's rays have. In addition, one should not forget about the general benefits of the sun for all life on the planet.
You should not think that the sun's rays are so useful that you can be uncontrollably under them. In addition to the mass of benefits, they can cause just as much harm if you are not careful with them.
- With prolonged exposure, sunburn appears - this is a protective mechanism of the body that tries to cope with the harmful effects of ultraviolet rays. If at the first redness you do not take measures and do not protect the skin, then you can easily get a serious burn. In some people, it even leads to skin cancer.
- You cannot look at the sun without sunglasses, as its strong brightness can blind or damage your eyesight.
- For those who suffer from dry skin, it is contraindicated to stay in the sun for a long time without a moisturizer, as the rays are even more capable of drying it out.
- If you do not protect your head with a panama or cap, you can get sunstroke or heat. Its manifestations are: fever, increased heart rate, nausea. Sometimes people lose consciousness and even die, unless urgent help is provided and the person is not taken to a cool, dark room, applying ice compresses.
Therefore, it is imperative that when in direct sunlight, you should take precautions and protect your head with a light-colored hat, drink more fluids, and wear glasses. Also try to avoid being outside when the sun is at its zenith.
The sun is a heavenly body that gives warmth and light to all life on the planet, rising in the east. But in addition to benefit, it can also bring harm, and this should not be forgotten.
I'm serious at school fond of geography. While my classmates were reading love novels, I read encyclopedias. I wanted as much as possible learn about spaceatmosphere and universe. I paid special attention to the study of the role sun on our planet. Therefore, where it rises, I know exactly. :)
Where the sun rises
The sun is a star, and the closest star to our planet. But at the same time it is FROMThe sun is about 150 million km away from us. It is even difficult to imagine such a distance or compare it with something ....
Some people think that The sun is moving during the day in the sky, and someone is sure that it is static, and the earth is moving. But be that as it may, During the day, the Sun rises and sets. Every day in our life there is morning and evening.
Always and at any time of the year. If it's winter outside and the sun appears late in your country, then be sure sunrise happened anyway in the east, even if the sun reached you only at 7 in the morning.
Lands of the Rising Sun
There are several versions of who sees the sunrise first
- "Japan - Land of the Rising Sun", - so the Japanese like to talk about themselves. The rising sun on their flag means the flowering of the country, the rise of consciousness to a new level. They are consider their nation elected. Besides, Japan is the most extreme country in the East. Therefore, the Sun rises here, they say.
- . Someone believes that the Sun is seen first here, but the confusion is due to the fact that through Alaska just passes the line of change of day.
- Chukotka. Many believe that the Sun rises in Russia. Since through the Bering Strait, between America and Russia there is a border that separates the day. If in America, in Alaska the day is over, then just in Chukotka, the sun begins to rise. It turns out that the first to see the Sun are not the Japanese, but the Russians.
But which country would not have sunrise, the main thing is that The sun did not get tired of appearing every day. Otherwise, if the Sun goes out, and life on Earth ends.
