IRIDIUM 47 DEB, 40254
Orbit data source: Space-Track
IRIDIUM 47 DEB, 40254 is space debris in LEO originally from a launch on Sat, 20 Dec 1997 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.
