It comes from pieces that fall of satellites or that are blown of satellites when they collide or are blasted by a missile. Some of the space junk is also spent rocket stages.
Yes it is, space junk , space junk orbits the earth just above it atmoshpere . Space junk consists of debris from shuttle and rockets sent to the moon or to explore deep space. ░¤JΣ†¤░
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.
Space junk is mainly old satellites that we never bothered to bring back to earth. In other words, we launch space junk to space, but it's not junk at launch. Get it?
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.
space junk is created by humans with out purpose, is created by the satellites , space rockets ..etc. the space junk is the little parts that fall or get of these things

bits of space craft remains and it comes from earth
Anything, junk or otherwise, that orbits the earth will eventually fall back to earth and burn up (mostly). A few chunks do make it all the way to the ground and have been found by people.
Objects in near-Earth orbits will decay over time and fall back into the atmosphere and be destroyed. Objects in higher orbits will remain there until retrieved. There are thousands of pieces of "space junk" cluttering up the orbital area, and sometimes they collide with each other - creating even MORE "space junk".

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.

An object which orbits a planet is generically called a satellite. The moon is a satellite, but so are artificial satellites, and occasionally asteroids and space junk.
Space junk gets into space by astronauts dropping there gloves or a tool when they are working at a space station, or things that come off a space station. in other words the only space junk there is, is from us humans.
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.
