OBJECT B, 58503 (Decayed)
Orbit data source: Space-Track
OBJECT B, 58503 was a satellite owned by Tuoyuan Shikong (CN) in LEO that was launched on Mon, 04 Dec 2023 UTC via a GUSHENXING 1 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. This object's orbit decayed before it could be identified.
