Man-made objects in space that no longer serve any useful purpose are known as space debris, space waste, space junk or orbital debris. A wide range of objects from neglected satellites to entire spent rocket bodies and their fragments fall under the definition of space waste. Today the increasing number of space waste is a growing problem, threatening that the area of low Earth orbit might become unusable.
