and you'll find them here on this thread

Is it possible for two orbiting satellites to collide?
Collisions between satellites are indeed unlikely, but their likelihood increases rapidly with the number of satellites: increase the number of satellites 10 times and, other things being equal, the likelihood of collision grows 100-fold.
It all depends on the orbits of course. Most satellites move in low-altitude Earth orbit, 600-1000 kilometer above the ground. At any time, this space is filled by thousands of pieces of matter--satellites, rocket stages, cast-off pieces of hardware (like weights used to slow down satellite spin), etc., about 100,000 pieces, most of them fragments from exploding rockets, but also including some 7500 larger accountable pieces of space hardware. Space is huge, but all these are moving rapidly. Luckily, all motions are essentially in the same direction (west to east, chosen to take advantage of the Earth's rotation) with almost the same speed. Even so, that speed is enormous, and collisions still may occur, since the orbits make different angles with the Earth's equator.
So far, the problem is not serious.
