Can space junk play a role in blocking meteors and protecting the earth?

Obviously not, the location of space junk is erratic, and the volume is not large. And the impact of a meteor hitting the earth is very strong, and space junk cannot stop it.

From some angles, if a meteor passes by and then hits space junk, it does play a role in protecting the earth. But the harm of space junk is often much greater than that.

1.It can only be said that part of it is blocked, and the remaining part will be dispersed due to the impact of the meteor to increase the loss.

2.If meteors do come to Earth, space junk alone is insignificant, and for now, the future is still very safe.

Since the beginning of human spaceflight, more than 9,000 satellites have been launched into orbit, but with the increase in the frequency of launches, space has become more and more crowded, in addition to the satellites currently operating in Earth orbit, there are about 100 million pieces of space junk.

Space junk floats in the air, but it doesn't have a very big impact on the Earth. After all, the yield of space junk is very low, and it will not cause so-called environmental pollution, and it will not be harmful to the earth's atmosphere.

I don't think it will affect it, because it's really too far away to make any difference.

No, because the garbage in space moves in a circular motion in the Earth's outer orbit, and the distance of its orbit is greater than the thickness of the atmosphere, so it will not affect the Earth's environment and atmosphere.

If space junk falls to the ground, it will pose a great threat to the safety of people and property, and at the same time, artificial satellites may collide with space junk, resulting in damage to satellites and great losses.

Space junk has no effect on the earth itself, but it is harmful to satellites and other aircraft, and if it hits, it will damage the aircraft. Now people have invented flying machines that can grab this garbage and use it to clean it up.

Space junk can interfere with the space observation of scientists on the ground, and it can also have a huge impact on space missions, and can also lead to space accidents. China has now invented a special aircraft to pick up garbage.

1.Space junk is useless man-made objects orbiting the Earth; Space junk can be made up of satellite debris, paint, dust, and entire spacecraft wreckage.

2.If space junk collides with an operating satellite, a manned spacecraft or the International Space Station, it can endanger equipment and even the lives of astronauts.

3.Unused satellites can be pushed off orbit, defenses can be evaded, and there are also aircraft that specialize in garbage.

Too much space junk is a huge hidden danger to the earth, so how to clean up space junk.

Don't underestimate this space junk, because of the extremely fast flight speed (6 7 kilometers per second), they all contain huge lethality, a 10-gram piece of space junk crashed into a satellite, which is equivalent to two cars colliding head-on at a speed of 100 kilometers per hour - the satellite will be pierced or destroyed in an instant! Imagine if you hit a manned spacecraft ......

And humans have no control over the flight trajectory of space junk, only roughly**. This garbage is like those driverless, random cars on the highway, you don't know when it brakes and when it changes lanes. They are the biggest potential "perpetrators" of cosmic traffic accidents and a huge threat to both astronauts and vehicles.

At present, the space around the earth is quite open, and the probability of space junk colliding in space is very small, but once it collides, it will be devastating. Even more of a headache for aerospace experts is the "avalanche effect" – each impact does not annihilate the debris against each other, but creates more debris, and each new debris is a new source of collision hazard. If one day, when the earth is surrounded by these space junks, what will be the path for mankind to explore the universe?
