You're viewing an Uncataloged Satellite

Recently launched and/or uncataloged satellites may have evolving metadata. Metadata may include but not limited to: Owner, Maufacturer, Bus, Motor, and Mission.

OBJECT C, 66668 is a satellite in SSO that was launched on Fri, 28 Nov 2025 UTC via an FALCON 9 launch vehicle from the Air Force Western Test Range (AFWTR). 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.
