OBJECT D, 54685
Orbit data source: Space-Track
OBJECT D, 54685 is a Chinese satellite in SSO that was launched on Fri, 09 Dec 2022 UTC via a JIELONG-3 launch vehicle from the Yellow Sea Launch Area, China (YSLA). 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.
