ATLAS 5 CENTAUR R/B, 39475

Orbit data source: Space-Track

ATLAS 5 CENTAUR R/B, 39475 is space debris in LEO originally from an American launch on Fri, 06 Dec 2013 UTC via an ATLAS V 501 launch vehicle 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.
