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 J, 61902 is a satellite owned by Yunyao yuhang (CN) in SSO that was launched on Mon, 11 Nov 2024 UTC via a LIJIAN-1 launch vehicle from the Jiuquan Satellite Launch Center, China (JSC). 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.
