OPS 4682 DEB, 55120
Orbit data source: Space-Track
OPS 4682 DEB, 55120 is space debris in LEO originally from a launch on Sat, 03 Apr 1965 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.
