SL-16 R/B, 25400
Orbit data source: Space-Track
SL-16 R/B, 25400 is space debris in SSO originally from a launch on Fri, 10 Jul 1998 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.
