KUIPER-00451

KUIPER-00451 is an active satellite operated by Amazon (United States), launched on 2026-04-30 from Guiana Space Centre, Kourou. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 476 km and 493 km with an inclination of 51.9°. It travels at approximately 27,451 km/h (7.63 km/s), completing one full orbit every 94 minutes — that’s roughly 15.27 orbits per day. It is part of the Kuiper constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~1–3 years. Orbital Radar tracks KUIPER-00451 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

KUIPER-00451 orbits at an average altitude of 485 km in the core of Low Earth Orbit, the most heavily utilised altitude band. The balance of moderate drag (limiting debris accumulation) and short signal path (enabling low-latency links and high-resolution imaging) makes this regime the default for most commercial and government missions. Within ±50 km of KUIPER-00451’s average altitude, there are currently 8,090 active payloads and 222 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 46.4% of all active satellites. With an inclination of 51.9°, KUIPER-00451 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 12,360 active satellites in total, of which 7,504 share a similar altitude band with KUIPER-00451.
