COSMOS 2143 DEB, 57720
Orbit data source: Space-Track
COSMOS 2143 DEB, 57720 is space debris in LEO originally from a launch on Thu, 16 May 1991 UTC launched from the Plesetsk Missile And Space Complex (PKMTR). Debris objects in space refer to the collection of defunct objects orbiting the Earth. Examples of debris include non-operational satellites, rocket bodies, and fragments generated from explosions, collisions, or faulty payload assembly.
