SL-12 R/B(2), 28918

Orbit data source: Space-Track

SL-12 R/B(2), 28918 is space debris in MEO originally from a launch on Sun, 25 Dec 2005 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.
