TRANSIT 11 DEB, 11991
Orbit data source: Space-Track
TRANSIT 11 DEB, 11991 is space debris in LEO originally from a launch on Fri, 28 Jan 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.
