COSMOS 1818 COOLANT, 36936
Orbit data source: Space-Track
COSMOS 1818 COOLANT, 36936 is space debris in LEO originally from a launch on Sun, 01 Feb 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.
