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 D, 51949 is a Chinese satellite in LEO that was launched on Sat, 05 Mar 2022 UTC via a CHANG ZHENG 2C 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.
