📖 About This Object
STARLINK-1958 is an active satellite operated by SpaceX (United States), launched on 2021-02-04 from Cape Canaveral, Florida. It orbits in Low Earth Orbit (LEO) at altitudes between 220 km and 223 km with an inclination of 53.0°. It travels at approximately 27,993 km/h (7.78 km/s), completing one full orbit every 89 minutes — that’s roughly 16.21 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-1958 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
STARLINK-1958 orbits at an average altitude of 222 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-1958’s average altitude, there are currently 74 active payloads and 2 tracked debris or rocket body fragments — notable neighbours include STARLINK-1411, STARLINK-1606, STARLINK-1665. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 53.0°, STARLINK-1958 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 12,360 active satellites in total, of which 65 share a similar altitude band with STARLINK-1958.
🔗 Starlink Constellation

This satellite is part of SpaceX's Starlink mega-constellation, the largest satellite constellation ever deployed. Starlink provides low-latency broadband internet to users in 70+ countries using thousands of satellites in low Earth orbit at altitudes between 540–570 km. Each satellite weighs approximately 260–300 kg (v1.5/v2 Mini) and uses krypton-ion thrusters for station-keeping and end-of-life deorbiting. The constellation is designed for autonomous collision avoidance manoeuvring. As of 2026, approximately 9,850 Starlink satellites are operational, with SpaceX targeting 12,000 in the initial shell and up to 42,000 approved.

❓ Frequently Asked Questions
