COSMOS 1867 COOLANT, 39665
Orbit data source: Space-Track
COSMOS 1867 COOLANT, 39665 is space debris in LEO originally from a launch on Fri, 10 Jul 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.
