LEMUR 2 NIMBUS2000

LEMUR 2 NIMBUS2000 is an active satellite operated by Spire Global (United States), launched on 2024-01-31 from RLLC on the Lemur SSA 1-4 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 438 km and 452 km with an inclination of 97.4°. It travels at approximately 27,530 km/h (7.65 km/s), completing one full orbit every 93 minutes — that’s roughly 15.40 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 ~1–3 years. Orbital Radar tracks LEMUR 2 NIMBUS2000 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

LEMUR 2 NIMBUS2000 orbits at an average altitude of 445 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 LEMUR 2 NIMBUS2000’s average altitude, there are currently 7,810 active payloads and 155 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 44.7% of all active satellites. With an inclination of 97.4°, LEMUR 2 NIMBUS2000 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. United States operates approximately 12,413 active satellites in total, of which 7,478 share a similar altitude band with LEMUR 2 NIMBUS2000.
