OBJECT D, 100717
Orbit data source: Space-Track
OBJECT D, 100717 is a Chinese satellite in LEO that was launched on Thu, 17 Sep 2026 UTC launched from the Wenchang Satellite Launch Center (WSC). 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.
