SL-8 R/B, 15625
Orbit data source: Space-Track
SL-8 R/B, 15625 is space debris in LEO originally from a launch on Thu, 21 Mar 1985 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.
