STARLINK-1547

STARLINK-1547 is an active satellite operated by SpaceX (United States), launched on 2020-09-03 from Cape Canaveral, Florida on the Starlink V1.0-L11 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 272 km and 276 km with an inclination of 53.0°. It travels at approximately 27,882 km/h (7.74 km/s), completing one full orbit every 90 minutes — that’s roughly 16.01 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 Starlink constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is weeks to months. Orbital Radar tracks STARLINK-1547 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

STARLINK-1547 orbits at an average altitude of 274 km in the lower reaches of Low Earth Orbit, where atmospheric drag is significant and orbital lifetimes are measured in months to a few years. This is the busiest corridor in space — home to crewed spacecraft, rapid-revisit imaging satellites and the densest part of the Starlink constellation. Within ±50 km of STARLINK-1547’s average altitude, there are currently 137 active payloads and 8 tracked debris or rocket body fragments — notable neighbours include STARLINK-1151, STARLINK-1143, STARLINK-1279. With an inclination of 53.0°, STARLINK-1547 passes over latitudes between 53.0°N and 53.0°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 12,413 active satellites in total, of which 110 share a similar altitude band with STARLINK-1547.
