EPSILON R/B, 41897
Orbit data source: Space-Track
EPSILON R/B, 41897 is space debris in HEO originally from a launch on Tue, 20 Dec 2016 UTC launched from the Kagoshima Space Center University Of Tokyo (KSCUT). 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.
