One may ask, “What is Orbital Debris?” Although we don’t see space junk in the sky, beyond the clouds and further than the eye can see, it enters low Earth orbit (LEO). LEO is an orbital space junk yard. There are millions of pieces of space junk flying in LEO. Most orbital debris comprises human-generated objects, such as pieces of space craft, tiny flecks of paint from a spacecraft, parts of rockets, satellites that are no longer working, or explosions of objects in orbit flying around in space at high speeds.
