The solar system is named after the sun, and the sun is the leader and manager of the solar system. We all know that in the universe, the mass is the most important. The larger the mass is, the stronger its gravity will be. The more planets, asteroids and other celestial bodies it will attract, and the wider its influence will be.
The sun is a star. From the day it was born, its gravity began to affect the operation of the surrounding celestial bodies. Slowly, the eight planets began to revolve around it, and other celestial bodies within its influence should also be subject to its management. The mass of the sun accounts for 99.84% of the total mass of the solar system, which huge mass difference makes its gravity absolutely dominant in the solar system, and other planets can only circle the sun obediently.
Someone once asked such a question: if one day the sun suddenly disappeared, what would be the fate of the earth? Some people may say that the solar system exists because of the existence of the sun. If the sun is gone, the solar system will no longer exist and the fate of the earth will be destroyed. Is that really the case? Now let’s do some research.
First of all, the greatest credit of the sun in the solar system is not the light and heat it produces. Of course, the greatest credit of the birth of life on earth is naturally the sun. But for the whole solar system, the greatest credit of the sun is actually its strong gravity. It is precisely because of its strong gravity that the eight planets and other kinds of asteroids can run stably and form a fixed orbit. No Then the celestial bodies of the solar system will fly around, and it is very difficult for an unstable galaxy to give birth to life and civilization.
The earth is a planet, it is also in rotation around the sun, and the speed of revolution reached 30 kilometers per second, this speed on the earth that is super high speed. Only when we walk out of the earth can we really see the speed of the earth’s revolution. We live on the earth. Because of gravity, we naturally can’t feel the earth moving at a high speed.
What happens to the earth when the sun suddenly disappears? The first thing many people think of is that soon the earth will fall into darkness and the humidity will drop sharply. Yes, this is what people living on the earth can see directly. When the sun suddenly disappears, it takes eight minutes for photons to reach the earth, so the earth will still have eight minutes of light. After eight minutes, no photons will reach the earth, and the earth will fall into darkness. It is the kind of real darkness that you can’t see. There are no stars or moon in the sky.
Then the temperature of the earth will drop rapidly. Soon, the earth will become a frozen planet. People can only live underground if they want to live. It’s just a small impact on the earth. In fact, the real threat to the earth is in space. When the sun disappears, the huge gravitational source accounting for 99.84% of the mass of the solar system disappears. What happens?
I believe many friends will think that the solar system may be in chaos. That’s right. When the sun disappears, the disappearance of the gravity boss makes the solar system free from strong gravity, and the eight planets and other asteroids are free without managers. At this time, the earth will fly out along the tangent of the orbit at the speed of 30km / s. Other planets and innumerable asteroids will also fly around. The collision events of celestial bodies in the solar system will occur frequently, and they will be smashed to pieces in many days.
At this time, the earth will not only face the disaster of the earth itself, but also face the threat of celestial body impact in space. If we are not careful, the earth will be hit by other celestial bodies or the earth will hit other celestial bodies. And the earth is so free of the constraints of the sun’s gravity, in addition to being thrown out, and the earth’s atmosphere will be instantly disturbed, many ground objects will fly into the mid air.
