OBJECT B, 61228 (Decayed)
Orbit data source: Space-Track
OBJECT B, 61228 was a Chinese satellite in LEO that was launched on Tue, 24 Sep 2024 UTC via a JIELONG-3 launch vehicle 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.
