What happens when the Earth is closer to the Sun, and what happens if the Earth gets closer to the S

First of all, a correction:

The average distance from the Earth to the Sun is 1 astronomical unit, and Venus is an astronomical unit from the Sun.

Mars is an astronomical unit.

If the Earth is from the Sun and the position of Venus, the astronomical unit, the temperature will be very high, slightly lower than the current temperature of Venus, but it will also reach more than 100 degrees, and it is estimated that there will be no life on the surface, but the beginning of life will start from the bottom of the earth or the sea. Whether there is life and this temperature difference should not have a big impact, the biggest difference is that the earth has water, and water is the source of life.

If the Earth is 2 astronomical units, the temperature will be very low and there may be no life.

But hundreds of millions of years ago, the difference between the earth's temperature and the present is very large, and species can also survive, indicating that the vitality of organisms is very strong, and there can be life in the high-pressure and low-temperature state of tens of thousands of meters on the earth's seabed, and it also shows that organisms can adapt to a very harsh environment. Without taking into account the evolution and adaptability of living things.

Biological life can survive under high pressure (such as the ocean floor), it doesn't matter if there is no oxygen (plants can absorb carbon dioxide to make oxygen), and low temperatures are no problem (penguins, underwater life in Antarctica, etc.), so there is life on the earth not because the ambient temperature is just right (we have adapted to the current environment), but because it has a lot of water resources by coincidence.

The Earth's orbit is an ellipse, and the Earth's distance from the Sun will not affect the temperature on the Earth.

The position of the Earth in orbit is divided into perihelion and aphelion. It is about the beginning of January and the aphelion in early July. The distance between the Sun and the Earth is not important to the change of the Earth's seasons, because the distance between the Sun and the Earth is 100 million kilometers at the farthest and 100 million kilometers at the closest in a year, which causes a difference of only 7% between the minimum and maximum values of solar heat energy available to the world in a year.

Due to the change of the direct point of the sun, the heat energy of the sun in the northern and southern hemispheres can be up to 57% different. Therefore, an important factor that determines the change of the earth's seasons is the location of the direct point of the sun. When the Earth passes perihelion, the sun shines directly on the southern hemisphere, and the southern hemisphere receives more solar heat than the northern hemisphere, so it is summer in the southern hemisphere, and the northern hemisphere is naturally in winter.

In the same way, when the earth passes aphelion, the sun shines directly on the northern hemisphere, and the northern hemisphere receives more solar heat than the southern hemisphere, so the northern hemisphere is summer, and the southern hemisphere is in winter.

If we follow the distance of 1 astronomical unit, it is true that the temperature of the earth is not suitable for survival. The temperature is comparable to that of Venus, about 450 to 500 degrees.

On the contrary, the Earth, which is 2 astronomical units away from the Sun, has not changed much, but the temperature has decreased slightly, about 15 to minus 80 degrees! 2 astronomical units is about the distance between Mars and the Sun!

The earth will burn up, everything will cease to exist, humanity will not be able to escape, the human category has no choice but to gradually migrate to the South Pole, why not move to the North Pole, because the North Pole is the ocean, so we must gradually migrate to the Antarctic continent. If the Earth were endlessly close to the Sun, humanity would simply become extinct until the Earth said goodbye to life, and the Earth's orbit was elliptical and varied at a different distance from the Sun. Every year around the beginning of January, it passes through the closest perihelion to the Sun, and at the beginning of July, it crosses the perihelion, which is the farthest from the Sun.

However, this distance change is almost negligible compared to the average radius of the Earth's revolution. The overall trajectory of the Earth Revolution is very stable. There will be no noticeable changes.

However, in a long time, the Sun will become a red supergiant in about 5 billion years, and its size will expand considerably, even engulfing several planets in orbit such as the Earth. So from this scale, we can say that the Earth is getting closer to the Sun and closer to the Sun.

The higher the temperature on Earth, the linear distance between the Earth's radius and the daytime will slowly decrease. Because the closer the Earth is to the Sun, the greater the intensity of the Sun's radiation, and the Earth's surface temperature will continue to rise. The Earth could be very fast The concept of very fast actually started with the concept of astronomical time, because he could catch up with the heat on Venus, and based on the time relationship between the Earth and the Sun, it was about 3.1 billion years.

The radius of the Earth and the Sun will be reduced to about 14.5 billion kilometres, or about 5 million kilometres. In other words, pollution caused by human activities has a relatively small impact on the Earth's environment. However, the hazards of natural occurrence are something that humans can never conquer, which is a bit like being uncontrollable, and secondly, he is helpless, and better yet, the earth has a period of life from middle age to old age before the sun bakes us.

As for the question of what would happen if the Earth got closer and closer to the Sun, that's it for today.

If the Earth gets closer to the Sun, then the Earth will get warmer and hotter, and the glaciers in the North and South Poles will melt completely, and the sea level will rise. It is possible to cause some very serious natural disasters that could lead to the possible extinction of all life on Earth.

The temperature on the earth's surface will get higher and higher, and the earth's plants will die in large numbers. The closer you get to the sun, the higher the temperature will be, and when the temperature exceeds a certain capacity, the plants on the earth will die in large numbers.

The temperature of the earth is getting higher and higher, the melting of glaciers affects the entire waters of the earth, many places will be greatly submerged, and the increase in ultraviolet radiation will cause physical harm to animals and people.

The birth of the earth is much like a fortuitous event

The Earth is a planet that we humans live on, and the planet is full of life and has a lot of life, but this is also the solar system.

The only planet with life, and the only planet with life among all the planets observed by human beings, because the conditions for the formation of life are too harsh, the formation of life must have water, and the temperature can not be too high, nor too low, of course, this is only the formation of life on our earth, and it does not mean that the formation of life in the entire universe needs these conditions, but these conditions are already very harsh, which leads to the birth of life on the earth as if it was an accidental event. <>

The Earth's distance from the Sun is just right

Earth is the third planet in the solar system to be close to the sun, so it can be said that the distance from the sun is just right. If the Earth is too far away from the Sun, it will be like Mars, Uranus.

Neptune is so cold, take Mars as an example, the structure of Mars is actually very similar to the Earth, known as the two sisters, but because Mars is too far away, the temperature is too low, and no life was formed; And if the Earth is too close to the Sun, then it will be like Venus and Mercury.

Similarly, the whole planet is unbearably hot all year round, the surface temperature is as high as a few days, and it is impossible for life to be born, so the distance between the sun and the earth is very important. <>

The coincidence of the earth has led to a reverie

After understanding that it is not easy to form life on the earth, some people will begin to ask questions, because the formation of life on the earth is really too coincidental, as if people are experimenting on a creature nowadays, and all the necessary conditions for survival are prepared, so people begin to speculate that maybe human beings are the objects of study that are raised, and some people will guess that maybe life on earth is the descendants of aliens, etc., the origin of human beings.

The problem of transplantation accompanies people, but the current technology does not give a reasonable explanation, I believe with the development of science.

Eventually, human answers will be found. <>

I think that there is a relationship between the earth being farther away from the sun and the closer to the omen, which will change the temperature of the cavity surface of the earth's surface and change the operating mechanism of the whole earth. I think that the proximity of the sun to the earth will have an impact on the earth, and the impact is greater than that of selling stove shirts.

Actually, I feel that it is related, if we are far away from the sun, we may not be able to receive the sun, and if we are closer, we may be burned.

The earth is a planet in the solar system, and the distance of the earth from the sun has a very great impact on the activation of our daily life cover, which will seriously affect the temperature of the stuffy hall on the ground.

Regarding the distance of the sun from people, it is necessary to combine the revolution and rotation of the earth, and also to see the latitude and time of people on the earth.

The earth revolves around the sun, and the orbit is an ellipse, and the sun is at a focal point of this ellipse, so the distance of the earth from the sun is related to the position of the earth in the orbit of the earth. On the summer solstice, the Earth is at aphelion, and the Earth is farthest from the Sun; During the winter solstice, the Earth is at perihelion, and the Earth is closest to the Sun. From perihelion to aphelion, that is, from the winter solstice to the summer solstice, the earth rotates and moves away from the sun; During the summer solstice and winter solstice, the Earth is getting closer and closer to the Sun.

It can be seen that the sun is the closest at the winter solstice. This is from a year, if you look at it from one day, how does the distance of the earth from the sun change?

If the Earth moves no other than its rotation, and its axis of rotation is perpendicular to the straight line between the Sun and the Earth, then at the same time people at the equator are closest to the Sun and people at the poles are farthest. However, the Earth rotates at an angle, so the difference between morning and evening is greater at the equator, and the greater the latitude (i.e., the farther away from the equator), the smaller the difference between the distance between the Sun at noon and between morning and evening.

If the Earth is completely stationary, the area in the middle hour is closer to the Sun than the area in the morning hour. However, the earth is not completely stationary, but is in a constant rotation and revolution, so the distance between the sun and the observer is related to the shape of the earth, the latitude of the earth, the sunrise time, the slow change in the direction of the earth's axis of rotation, and the slight influence of the gravitational pull of the planets on the earth's orbit, but the change in this distance is negligible compared to the straight-line distance of the sun and the earth.

It can be seen that on the same day, at different times, in different places, the sun is far and near from people. It's just that this distance is so small compared to the distance of the sun from the earth that it is not necessary to consider at all, just like the weight of a few hairs on a heavy elephant's body, which is negligible. So, in a day, in the same place, the sun should be the same distance from the earth in the morning and at noon.
