OBJECT M

OBJECT M (NORAD ID 100966) is a space object catalogued under South Korea, launched on 2026-10-07 from Naro Space Center, South Korea on the NeonSat launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. Independent catalogue analysis identifies this object as GBSat, attributed to KAIST. It orbits in Low Earth Orbit (LEO) at altitudes between 563 km and 581 km with an inclination of 97.7°. It travels at approximately 27,277 km/h (7.58 km/s), completing one full orbit every 96 minutes — that’s roughly 14.98 orbits per day. Its near-polar, sun-synchronous orbit means it passes over any given point on Earth at approximately the same local solar time, ideal for consistent Earth observation lighting conditions. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks OBJECT M in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OBJECT M orbits at an average altitude of 572 km in a sun-synchronous orbit (SSO), a specialised subset of LEO where the orbital plane precesses to maintain a constant angle relative to the Sun. This provides consistent lighting conditions on every pass — essential for Earth observation, weather monitoring and environmental science. Within ±50 km of OBJECT M’s average altitude, there are currently 1,225 active payloads and 543 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-3005, STARLINK-3090. This makes it one of the more crowded altitude bands, containing roughly 6.5% of all active satellites. With an inclination of 97.7°, OBJECT M passes over latitudes between 97.7°N and 97.7°S, providing near-global coverage including the polar regions. Polar and near-polar orbits are used for reconnaissance, weather monitoring and Earth-observation missions that need to image every part of the planet. South Korea operates approximately 64 active satellites in total, of which 21 share a similar altitude band with OBJECT M.
