When an object is in space, it is usually acted upon by some form of gravitational force from a large body of which keeps it some form of orbit. In addition to this, Newton's Laws pretty much state "things like to keep doing what they're doing". Space junk has no friction acting upon it to slow it's motion, so will continue to move in an orbital motion around some body in space, and not be pulled back down to say, Earth, because of balanced centripetal forces and whatnot. (Standard stop before the physics gets silly.)

How long can space junk stay in space?

Space junk can remain in Earth's orbit for many years, ranging from decades to hundreds of years, depending on its altitude and the density of the Earth's atmosphere at that level. Some larger pieces may even stay in orbit for thousands of years.


How does space junk in to space?

"Space Junk" gets into space because of us leaving materials behind when we visit space.


What happens to the junk thrown by astronomers in the space station and space shuttles Does it stay afloat?

It usually stays in orbit around the earth, and poses a serious threat to all orbiting satellites. Even a small object can destroy things at high speed. Most satellites can move around projected paths of junk thrown in space. Some astronomers use radio telescopes to track "Space Junk".


Is Saturn Space Junk?

No. Space junk consists of fragments of spacecraft left in space. Saturn is a planet.


Why does space junk form?

Because satellites are blown up, forming debris, which is called space junk


How does space junk get in space?

Space junk is usually the result of human-made objects that are no longer operational or have been discarded in space. This includes defunct satellites, spent rocket stages, fragments from collisions, and debris from missions. Over time, these objects can collide with each other, creating more debris and increasing the amount of space junk in orbit.


Does space junk interact with asteroids?

This would happen, space junk could collide with asteroids, but most space junk is close to the earth, away from the main asteroid belt. It would be more likely to collide with meteroids and other bits of space junk.

Is space junk real?

Yes, space junk is real. It consists of defunct satellites, spent rocket stages, and other debris left in orbit around Earth. This space debris poses a risk to active satellites and spacecraft in orbit.


What are other dangers in outer space?

well i think they would mostly be space junk check this out its the earth http://static.howstuffworks.com/gif/space-junk-4.jpg and all that white stuff is space junk orbiting earth.


How did space junk get where it is at?

Since the 1950's the United States and other nations have been sending satellites into space. Eventually they die and then turn into space junk. They stay there until, at some point, they return to earth as falling junk.
