ATLAS 5 CENTAUR DEB, 51477
Orbit data source: Space-Track
ATLAS 5 CENTAUR DEB, 51477 is space debris in HEO originally from a launch on Wed, 17 Sep 2014 UTC launched from the Air Force Eastern Test Range (AFETR). 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.
