OBJECT BF, 60521 (Decayed)
Orbit data source: Space-Track
OBJECT BF, 60521 was a satellite in LEO that was launched on Fri, 16 Aug 2024 UTC via an FALCON 9 launch vehicle from the Air Force Western Test Range (AFWTR). 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.
