OBJECT C, 100403
Orbit data source: Space-Track
OBJECT C, 100403 is a satellite owned by Rocket Lab (US) in LEO that was launched on Thu, 20 Aug 2026 UTC launched from the Rocket Lab Launch Complex (RLLC). 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.
