OBJECT G, 40905
Orbit data source: Space-Track
OBJECT G, 40905 is a Chinese satellite in SSO that was launched on Sat, 19 Sep 2015 UTC via a CHANG ZHENG 6 launch vehicle from the Taiyaun Space Center, China (TSC). 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.
