COSMOS 663 DEB, 53881
Orbit data source: Space-Track
COSMOS 663 DEB, 53881 is space debris in LEO originally from a launch on Thu, 27 Jun 1974 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.
