OBJECT AH

OBJECT AH is an active satellite operated by Unknown, launched on 2025-03-15 from Vandenberg Space Force Base, United States on the Transporter-13 launch. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. Independent catalogue analysis identifies this object as NILA, attributed to Hex20Labs. It orbits in Low Earth Orbit (LEO) at altitudes between 470 km and 480 km with an inclination of 97.4°. It travels at approximately 27,470 km/h (7.63 km/s), completing one full orbit every 94 minutes — that’s roughly 15.30 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. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks OBJECT AH in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OBJECT AH orbits at an average altitude of 475 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 AH’s average altitude, there are currently 11,098 active payloads and 191 tracked debris or rocket body fragments — notable neighbours include STARLINK-1017, STARLINK-1039, STARLINK-1047. This makes it one of the more crowded altitude bands, containing roughly 56.5% of all active satellites. With an inclination of 97.4°, OBJECT AH passes over latitudes between 97.4°N and 97.4°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.
