OBJECT J, 59781
Orbit data source: Space-Track
OBJECT J, 59781 is a satellite owned by Byuro 1440 (CIS) in SSO that was launched on Thu, 16 May 2024 UTC via a SOYUZ-2-1B launch vehicle from the Plesetsk Missile And Space Complex (PKMTR). 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.
