OBJECT B, 66176
Orbit data source: Space-Track
OBJECT B, 66176 is a satellite owned by CASC (CN) in SSO that was launched on Sun, 26 Oct 2025 UTC launched from the Xichang Space Center, China (XSC). 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.
