OBJECT C, 65546
Orbit data source: Space-Track
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 C, 65546 is a satellite owned by CAST (CN) in LEO that was launched on Sat, 06 Sep 2025 UTC via a CHANG ZHENG 6A launch vehicle from the Taiyaun Space Center, China (TSC). 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.
