OBJECT C, 100239 (Decayed)
Orbit data source: Space-Track
OBJECT C, 100239 was a satellite owned by Changzheng H. (CN) in SSO that was launched on Wed, 05 Aug 2026 UTC launched 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. This object's orbit decayed before it could be identified.
