LEMUR-2-LAILA

LEMUR-2-LAILA is an active satellite operated by Spire Global (United States), launched on 2025-11-28 from Vandenberg SFB, California. As a relatively recent addition to the catalogue, its orbital elements are well-characterised. It orbits in Low Earth Orbit (LEO) at altitudes between 500 km and 504 km with an inclination of 97.4°. It travels at approximately 27,416 km/h (7.62 km/s), completing one full orbit every 95 minutes — that’s roughly 15.21 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 ~3–10 years. Orbital Radar tracks LEMUR-2-LAILA in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

LEMUR-2-LAILA orbits at an average altitude of 502 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-LAILA’s average altitude, there are currently 9,599 active payloads and 244 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 55.1% of all active satellites. With an inclination of 97.4°, LEMUR-2-LAILA 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 12,360 active satellites in total, of which 8,978 share a similar altitude band with LEMUR-2-LAILA.
