OBJECT AD

OBJECT AD (NORAD ID 59125) is a space object catalogued under Unknown, launched on 2024-03-04 from Vandenberg SFB, California on the Transporter-10 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 452 km and 464 km with an inclination of 97.6°. It travels at approximately 27,504 km/h (7.64 km/s), completing one full orbit every 94 minutes — that’s roughly 15.36 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 AD in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

OBJECT AD orbits at an average altitude of 458 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 AD’s average altitude, there are currently 7,926 active payloads and 166 tracked debris or rocket body fragments — notable neighbours include STARLINK-1008, STARLINK-1012, STARLINK-1017. This makes it one of the more crowded altitude bands, containing roughly 45.5% of all active satellites. With an inclination of 97.6°, OBJECT AD passes over latitudes between 97.6°N and 97.6°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.
