What is Space Junk?

Space junk, also called orbital debris or space trash, is a collection of objects made by humans that are in orbit in space. A huge number of these objects were part of humanity's expeditions into space, and some are bits and pieces of material formed when human-made objects collide with other solar objects. These materials range in size, from some as small as 0.4 inches to some as big as 4 inches and there are estimated to be as many as 170 million objects in space.
