I heard that the collision of US and Russian satellites with 12,000 pieces of debris orbiting the ea

Yes, of course!! It will be a great threat to artificial satellites flying over the earth! There should be no threat to the ground, because the earth has a natural umbrella, the atmosphere!!

Those debris fell into the atmosphere and burned up after friction! Become a shooting star! It won't fall to the ground!

Oh, and at worst, it will be a deterrent to other countries that want to develop their space industry.

The United States is really amazing at this hand, even if it loses a satellite worth hundreds of millions, it is worth it! As for the 12,000 pieces, we don't have to worry about it if we live in Mother Earth's arms, you can go out for the night with your lover and partner as usual......On the contrary, at the candlelight dinner, you hold his hand and look up at the night sky to watch the meteor shower fall, and 12,000 pieces of synthetic metal will be destroyed to witness the love between the two of you!

Although there is so much garbage, the news of damage to satellites and space stations is still rarely heard.

NASA says the chance of debris hitting someone on the ground is very low, at only one in 3,200. Since up to 75% of the earth's surface is sea, satellites are also very likely to fall directly into the sea, and it doesn't matter if the satellite hits the earth, and it is only the size of an iron ball when it falls, and it will basically burn up.

All satellites without power will be affected by the gravitational pull of the earth and fall to the ground, but because of the earth's atmosphere, the satellite burns up in the atmosphere during the fall, and there is not much harm to the ground. And the armies of various countries will not let it go. Rest assured.

Stoned the Americans and the Japanese!! Hahahahahaha Chinese ha

Hello! This is a physical problem, but with the development of human beings, more and more space junk, such as discarded artificial satellites, space stations, aircraft, etc., take care of the earth from time to time, and to some extent, this also poses a threat to people's safety.

First of all, the principle of operation of artificial satellites.

According to the analysis of the force on the satellite, the satellite is affected by the gravitational force of the earth, and in order to provide the centripetal force of the satellite around the earth, it is manifested as pulling the satellite towards the earth; When the satellite moves in a circular motion, it will inevitably produce a centrifugal force due to a certain speed, which is manifested as moving away from the earth. Satellites operate under the interaction of centripetal and centrifugal forces. If the satellite accelerates, it will inevitably make its orbit higher, i.e. away from the Earth, and vice versa.

Its trajectory is approximately elliptical. Its motion follows the theorems of the mechanics of the cow.

Secondly, the dynamics of artificial satellites.

The normal operation of the artificial satellite is equipped with an artificial engine and solar panels, which receive sunlight and convert it into solar energy, and the chemical energy obtained by the reaction of chemical reagents inside the satellite is finally manifested by the engine to power the artificial satellite by doing work on the engine.

Clause. 3. Because the abandoned artificial satellite cannot work normally, its power system cannot provide considerable power to make it orbit the earth, so that it cannot produce a centrifugal force that cancels out the earth's gravitational pull on it, so the satellite shows that it is constantly pulling the earth, which causes the satellite to hit the earth.

Finally, the earth is surrounded by dozens of kilometers of atmosphere, forming a protective layer on the earth, and the satellite is colliding with the earth at the same time, the relative speed of the two is extremely large, in the process of falling, the atmosphere continues to work on the surface of the satellite, producing high temperatures, so that the satellite continues to burn, the mass continues to decrease, and finally even if there is still part of the debris to the ground, compared with before, there is very little.

Therefore, the atmosphere is the protective layer of the earth, so that the earth is protected from the harm of space strangers, we must protect the atmosphere!

Hope mine can help you!

The orbit is not the same, but the calculation is wrong.
