OBJECT XW, 66910
Orbit data source: Space-Track
OBJECT XW, 66910 is an American satellite in LEO that was delivered to and deployed from the ISS. 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.
