OBJECT U, 42843

Orbit data source: Space-Track

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 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.
