NOAA 16 DEB, 42421

Orbit data source: Space-Track

NOAA 16 DEB, 42421 is space debris in SSO originally from a launch on Thu, 21 Sep 2000 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.
