OBJECT U, 101129
Orbit data source: Space-Track
OBJECT U, 101129 is a satellite in LEO that was launched on Tue, 20 Oct 2026 UTC via an FALCON 9 launch vehicle from the Air Force Eastern Test Range (AFETR). 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.
