OBJECT U, 42843
Orbit data source: Space-Track
OBJECT U, 42843 is a satellite in SSO that was launched on Fri, 14 Jul 2017 UTC via a SOYUZ-2-1A launch vehicle from the Tyuratam Missile And Space Complex (TTMTR). 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.
