SL-16 R/B, 17590
Orbit data source: Space-Track
SL-16 R/B, 17590 is space debris in LEO originally from a launch on Wed, 18 Mar 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.
