OBJECT B, 56744

Orbit data source: Space-Track

You're viewing an uncataloged RSO

Recently launched and/or uncataloged RSOs may have evolving metadata. Metadata may include the following, but is not limited to: Owner, Manufacturer, Bus, Motor, and Mission.

OBJECT B, 56744 is a satellite owned by KASI (KR) 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.
