Troublesome space junk , are they affected by gravity?

In the 60 years since the first space flight was achieved, humans have been sending rockets into space at incredible speeds. There were 114 rocket launches in 2018 alone, and that number is expected to climb steadily as more and more countries begin to develop their space programs. There have been thousands of launches over the past 60 years, and while such an achievement in just sixty years is impressive, the story also has its dark side.

Whenever a rocket is launched, a certain amount of material is thrown off, such as the rocket casing that falls off once the fuel is depleted. In addition, as satellites are decommissioned, disintegrate, or collide with other debris, more "space debris" is generated. At the beginning of the space age, there was not much thought about the slow accumulation of debris in near-Earth orbit, but this is undoubtedly a problem, or rather, there are now about 500,000 "space debris".

The nature of gravity is directly related to the problem of space debris in low Earth orbit. In open and harsh environments, materials tend to decompose and begin to metamorphose, especially when they are left behind due to accidents, **, etc. Over time, large fragments become medium fragments, and medium fragments become small fragments.

In total, there are about 500,000 pieces of space debris floating in our orbits, of which more than 20,000 are larger than 4 inches. Each larger piece of debris is continuously monitored by ground-based space agencies for potential impact on satellites.

Countless pieces of debris have been left in space over time, and given how quickly the pieces are moving, it could pose a real threat to future launch missions. Some space junk moves in orbit at speeds of up to 24,000 miles per hour, so collisions with even small objects can cause serious damage. As the launch window shrinks and the launch becomes more and more difficult, the problem seems to only get worse.

If it could gather all the space debris together, the space agency would be grateful, but that's not realistic. As mentioned earlier, the vast majority of these 500,000 pieces are less than 4 inches, which means they have a very small mass. Also, let's not forget that the Earth is very large, which means that a few hundred miles of three-dimensional space is huge enough.

And gravity depends on the mass of the object and its proximity, for space debris they are less mass and less proximity. In other words, different space debris has little gravitational effect on each other.

will be affected by gravity, and everything in the universe will be affected by gravity.

Anything in the sky is affected by gravity.

Space junk is also an object and is naturally affected by gravity.

Yes, anything in the sky will be affected.

Definitely, gravitational pull will be applied nearby.

There should be a little, but not much.

Yes, after all, space junk is also an object.

Space junk is not gravitationally attracted in space.

Definitely, but less affected by gravity.

It's just that it's less affected by gravity.

After the rocket is launched, the booster, fairing and other wreckage will fall back to the earth, most of them will burn up when entering the atmosphere at high speed, even if it is not completely burned, many times experts will estimate a rough fall range, early warning and evacuation, the most thrilling one in the history of astronautics, is only a small piece of small rocket wreckage in the United States in 97, and a woman passed by.

1.The gravitational force is exactly equal to its centripetal force to make the satellite move in a uniform circular motion around the earth without stopping, half pairs, centrifugal force to be exact, but the centrifugal force is only related to the mass of the satellite, the instantaneous velocity and the radius of motion. After the satellite loses control, the space air is thin and the resistance is small, and its speed can be maintained for a long time, and it will not fall down when it reaches a certain speed in space, and only when its speed is reduced will it fall into the atmosphere and burn up.

2.Weightlessness is not getting farther and farther away from the Earth, it is simply that the gravitational pull on the sphere is equal to the centrifugal force. Weightlessness can be said to be falling, but it will never fall.

Gravitational force is only related to mass and distance, and weightlessness is simply the presence of a force that is opposite and equal to it, which never disappears.

There are a lot of small questions in your question, first answer your question about space junk: space junk is a very dangerous one, caused by human beings in the process of space station or satellite launch, because it floats in space, similar to meteorites, and will be attracted by the earth at any time to fall back to the ground or hit artificial satellites, bringing inconvenience to the use of artificial satellites, so it is strictly forbidden to create space junk in space.

Weightlessness: Weightlessness is a phenomenon caused by the loss of the earth's gravity caused by an object floating in the air, weightlessness does not mean a complete loss of gravity, but gravity is used to make the object move in a uniform circle around the earth. It only moves around the Earth when it reaches a certain height in the sky, and objects below this altitude fall to the ground due to gravity.

Space junk is a debris of space and is the product of human space activities, including rocket bodies and satellite bodies that have completed missions, rocket ejections, discarded objects in the process of aerospace missions, and debris caused by collisions between space objects, which are the main sources of pollution in the space environment. Millions of pieces of space debris are currently orbiting the Earth.

Since 1973, hundreds of pieces of space junk have fallen to Earth every year. However, due to the sharp friction between the atmosphere and the air, the garbage burns itself out before it passes through the atmosphere, and self-destructs under the protection of the atmosphere. However, at 11:55 a.m. EST (0:55 p.m. EDT on February 11, 2009), two communications satellites of the United States and Russia collided in space and generated a large amount of space junk, which is very likely to pose a threat to the International Space Station.

The scope of space is very large, relatively speaking, space junk is just a speck of dust in space, and so are satellites, the probability of two grains of dust meeting is very small, and there is also a collision when Sun Ran is a thing, but the probability is very small.

Space is very large, and the man-made astronauts are like grains of dust. And they all have their own fixed tracks. Collisions are not nothing, less pitiful. So far, it's been twice. They are China and the United States, Russia and the United States' abandoned satellites.

At 11:55 a.m. on February 10, 2009 (0:55 p.m. Beijing time on February 11, 2009), two U.S. and Russian lead communications satellites collided in space and generated a large amount of space junk, which is very likely to pose a bright threat to the International Space Station.

Now a space cleaner is being developed.
