You're viewing an uncataloged RSO

Recently launched and/or uncataloged RSOs may have evolving metadata. Metadata may include the following, but is not limited to: Owner, Manufacturer, Bus, Motor, and Mission.

OBJECT B, 51825 is a Chinese satellite in SSO that was launched on Sun, 27 Feb 2022 UTC via a CHANG ZHENG 8 launch vehicle from the Wenchang Satellite Launch Center (WSC). 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.

Not visible in the next 10 days
