OBJECT D, 43761
Orbit data source: Space-Track
OBJECT D, 43761 is a satellite in SSO that was launched on Mon, 03 Dec 2018 UTC via an FALCON 9 launch vehicle from the Air Force Western Test Range (AFWTR). Unknown objects in Earth's orbit typically refer to objects detected orbiting the Earth but have not yet been identified or cataloged. These objects could be anything from previously untracked satellites, spent rocket stages, debris from satellite collisions, or even natural meteoroids temporarily captured by Earth's gravity.
