OBJECT B, 56158
Orbit data source: Space-Track
OBJECT B, 56158 is a satellite owned by CNSA (CN) in LEO that was launched on Fri, 31 Mar 2023 UTC launched 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.
