SL-12 DEB, 29323

Orbit data source: Space-Track

SL-12 DEB, 29323 is space debris in HEO originally from a launch on Wed, 31 May 1989 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.
