OBJECT AF, 63239
Orbit data source: Space-Track
OBJECT AF, 63239 is a satellite in SSO that was launched on Sat, 15 Mar 2025 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.
