How fast does space junk travel?
Space junk travels as fast as all material that orbits the Earth or at about 17,500 miles per hour. This is fast enough to do damage to anything the junk encounters in orbit.
What are the dangers of space junk?
Everything is attracted to everything else by gravity. So, over time, space junk will attract other space junk and join with it. This larger amount of space junk could potentially come closer and closer to Earth (as the force of gravity on it is now greater, and with a greater mass it becomes more difficult to keep it in orbit). Eventually it might crash into the Earth, conditional on not burning up in the atmosphere. The orbit of space junk could bring it in contact with, destroy and make space junk of, commuication satellites, probes, telescopes etc.
How long can space junk stay in space?
if its in orbit, then it will stay up there forever unless something hits it close enough to the Earth for it to fall.
How can space junk harm us on earth?
The orbit of "space junk" could deteriorate, resulting in the junk falling to earth. If the item survives re-entry and reaches the earth's surface, it would cause the same damage as an equally sized meteorite, including damaging or destroying structures in the area, killing people, etc.
What kind of debris is in orbit around earth?
Space trash is a collection of old rocket boosters, junk from collisions (such as the collision between the Iridium satellite and the Russian spy satellite that happened about 6 months ago), and stuff dropped from one or another space missions such as the toolbox dropped from the ISS. NASA tracks about 10,000 pieces of "space junk" currently.

Why does Saturn have ring around it?
because astroids fling in to its orbit and also space junk does too

Does space junk crash into earth and other planets?
If space junk means man-made objects, very few have left Earth-orbit. Of the ones in Earth-orbit many crash each year but the vast majority burn up because of friction as they come at high speed through the upper atmosphere.
What things orbit?
Satellites and space 'junk'.
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".
Does space junk float in space?
In a sense. In space, technically no object floats, but rather is in continuous free fall. Contrary to popular belief there is gravity in space; it is the may force acting on objects. Most space junk is in orbit around Earth, meaning that, while Earth's gravity continuously pulls it down, it is moving so fast laterally that it never hits the ground.

A projectile that falls around the earth is?
a meteorite, or just debris from space junk
What contributes to making space junk?
Any waste materials in space. All satellites have a lifetime and after they have expired, the earth has no control over them and it floats aimlessly (junk). Also, meteorites can crash into a satellite (as well as other disasters) and it is blasted off orbit and becomes junk materials in space.
