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 A, 66175 is a satellite owned by Yaogan Zongti (CN) in SSO that was launched on Sun, 26 Oct 2025 UTC via a CHANG ZHENG 3B launch vehicle from the Xichang Space Center, China (XSC). 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.
