COSMOS 1900 DEB, 43500
Orbit data source: Space-Track
COSMOS 1900 DEB, 43500 is space debris in LEO originally from a launch on Sat, 12 Dec 1987 UTC launched from the Tyuratam Missile And Space Complex (TTMTR). 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.
