N-1 R/B, 8710

Orbit data source: Space-Track

N-1 R/B, 8710 is space debris in LEO originally from a launch on Sun, 29 Feb 1976 UTC launched from the Tanegashima Space Center (TNSTA). 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.
