ATLAS 5 CENTAUR R/B, 40978

Orbit data source: Space-Track

ATLAS 5 CENTAUR R/B, 40978 is space debris in LEO originally from an American launch on Thu, 08 Oct 2015 UTC via an ATLAS V 401 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.
