ATLAS 5 CENTAUR DEB, 55850
Orbit data source: Space-Track
ATLAS 5 CENTAUR DEB, 55850 is space debris in HEO originally from a launch on Wed, 17 Oct 2018 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.
