PEGASUS DEB, 39921
Orbit data source: Space-Track
PEGASUS DEB, 39921 is space debris in LEO originally from a launch on Thu, 19 May 1994 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.
