THORAD AGENA D DEB, 4187 (Decayed)
Orbit data source: Space-Track
THORAD AGENA D DEB, 4187 was space debris in LEO originally from a launch on Tue, 30 Sep 1969 UTC launched from the Air Force Western Test Range (AFWTR). 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.
