PAGEOS 1 DEB, 2511

Orbit data source: Space-Track

PAGEOS 1 DEB, 2511 is space debris in LEO originally from a launch on Fri, 24 Jun 1966 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.
