What is space debris? Space debris is defined as all non-functional, human-made objects, including fragments and elements thereof, in Earth orbit or re-entering into Earth’s atmosphere. Human-made space debris dominates over the natural meteoroid environment, except around millimeter sizes.

All human-made space objects result from the about thousands of launches conducted since the start of the space age. The majority of the cataloged objects, however, originate from in-orbit break-ups – more than 290 explosions – as well as fewer than 10 known in-orbit collisions.
