COSMOS 1261 DEB, 48264 (Decayed)
Orbit data source: Space-Track
COSMOS 1261 DEB, 48264 was space debris in HEO originally from a launch on Tue, 31 Mar 1981 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.
