You're viewing an Uncataloged Satellite

Recently launched and/or uncataloged satellites may have evolving metadata. Metadata may include but not limited to: Owner, Maufacturer, Bus, Motor, and Mission.

OBJECT L, 65129 is a satellite owned by GeeSpace (CN) in LEO that was launched on Fri, 08 Aug 2025 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.
