OBJECT E, 56747
Orbit data source: Space-Track
OBJECT E, 56747 is a South Korean satellite in SSO that was launched on Thu, 25 May 2023 UTC via an NURI launch vehicle from the Naro Space Center, South Korea (NSC). 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.
