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.
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.
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.
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.
Space junk comes from defunct satellites, spent rocket stages, and debris from spacecraft collisions or explosions. Over time, these objects break apart and create smaller fragments that continue to orbit Earth. The accumulation of space junk poses a threat to operational satellites and space missions in Earth's orbit.
Space launches, to get astronauts into space, or to place satellites in Earth orbit, cause unintentional debris as rocket stages are jettisoned and explosive bolts fire. The debris generated travels at huge speeds and remains in orbit for many years. Satellites come to the end of their life, when batteries fail, or electronics wear out and are left in their orbits to naturally decay and fall back to Earth. Finally,the worst form of space junk is the deliberate disintegration of a target satellites by the testing of new space weapons. These weapons are used to show off the technological abilities of nations and as a sign of strength. We are making a prison for ourselves since there are millions of pieces of junk in space and when the Shuttle hit a fleck of paint in space it very nearly blew a hole in the cockpit glass.

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.
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.
the moon, space junk, man made satalites and a space stationn.
No. Space junk consists of fragments of spacecraft left in space. Saturn is a planet.
