ERS 1 DEB, 48172 (Decayed)
Orbit data source: Space-Track
ERS 1 DEB, 48172 was space debris in SSO originally from a launch on Wed, 17 Jul 1991 UTC launched from the French Guiana (FRGUI). 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.
