OBJECT D, 100128
Orbit data source: Space-Track
OBJECT D, 100128 is an American satellite in HEO that was launched on Tue, 21 Jul 2026 UTC launched from the Air Force Eastern Test Range (AFETR). 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.
