DELTA 4 DEB, 51481 (Decayed)
Orbit data source: Space-Track
DELTA 4 DEB, 51481 was space debris in LEO originally from a launch on Fri, 12 Jan 2018 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.
