OBJECT A, 56731
Orbit data source: Space-Track
OBJECT A, 56731 is a satellite owned by CASC (CN) in LEO that was launched on Sun, 21 May 2023 UTC via a CHANG ZHENG 2C 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.
