KUIPER-00158

KUIPER-00158 is an active satellite operated by Amazon (United States), launched on 2025-09-25 from Cape Canaveral, Florida. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 624 km and 626 km with an inclination of 51.9°. It travels at approximately 27,174 km/h (7.55 km/s), completing one full orbit every 97 minutes — that’s roughly 14.81 orbits per day. Its near-circular orbit (eccentricity close to zero) means it maintains a very consistent altitude throughout each revolution. It is part of the Kuiper constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~10–25 years. Orbital Radar tracks KUIPER-00158 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

KUIPER-00158 orbits at an average altitude of 625 km in the mid-LEO band, where atmospheric drag is minimal but radiation exposure remains manageable. Objects at this altitude persist for decades to centuries, making debris mitigation critical. This regime is popular for remote sensing constellations and scientific instruments that need stable, long-duration orbits. Within ±50 km of KUIPER-00158’s average altitude, there are currently 815 active payloads and 803 tracked debris or rocket body fragments — notable neighbours include ONEWEB-0050, STARLINK-36132. With an inclination of 51.9°, KUIPER-00158 passes over latitudes between 51.9°N and 51.9°S, covering most populated land masses in both hemispheres. This mid-inclination band balances global coverage with efficient launch energy requirements. United States operates approximately 12,339 active satellites in total, of which 350 share a similar altitude band with KUIPER-00158.
