OBJECT G, 63988
Orbit data source: Space-Track
OBJECT G, 63988 is a Chinese satellite in SSO that was launched on Wed, 14 May 2025 UTC via a CHANG ZHENG 2D launch vehicle from the Jiuquan Satellite Launch Center, China (JSC). 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.
