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 AA, 43900 is a satellite in SSO that was launched on Thu, 27 Dec 2018 UTC via a SOYUZ-2-1A launch vehicle from the Vostochny Cosmodrome (VOSTO). 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.
