THOR ABLESTAR DEB, 38521

Orbit data source: Space-Track

THOR ABLESTAR DEB, 38521 is space debris in LEO originally from a launch on Sat, 28 Sep 1963 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.
