OBJECT C, 100653
Orbit data source: Space-Track
OBJECT C, 100653 is a satellite owned by PLA SSF (CN) in LEO that was launched on Thu, 10 Sep 2026 UTC via a CHANG ZHENG 4B launch vehicle from the Jiuquan Satellite Launch Center, China (JSC). 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.
