OBJECT A, 100366
Orbit data source: Space-Track
OBJECT A, 100366 is a Chinese satellite in SSO that was launched on Mon, 17 Aug 2026 UTC launched 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.
