📖 About This Object
STARLINK-3306 is an active satellite operated by SpaceX (United States), launched on 2021-12-18 from Vandenberg Space Force Base, United States on the Starlink Group 4-4 launch. It orbits in Low Earth Orbit (LEO) at altitudes between 200 km and 208 km with an inclination of 53.2°. It travels at approximately 28,030 km/h (7.79 km/s), completing one full orbit every 89 minutes — that’s roughly 16.41 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-3306 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-3306 orbits at an average altitude of 204 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-3306’s average altitude, there are currently 23 active payloads and 3 tracked debris or rocket body fragments — notable neighbours include STARLINK-1274, STARLINK-1284, STARLINK-1338. This is a relatively sparse altitude band, containing less than 1% of all active satellites. With an inclination of 53.2°, STARLINK-3306 passes over latitudes between 53.2°N and 53.2°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 13,340 active satellites in total, of which 18 share a similar altitude band with STARLINK-3306.
🔗 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
STARLINK-3306 orbits in Low Earth Orbit (LEO) at altitudes between 200 km (perigee) and 208 km (apogee), with an average altitude of approximately 204 km. It completes one orbit every 89 minutes, travelling at approximately 28,030 km/h (17,417 mph).
STARLINK-3306 is operated by SpaceX (United States). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 50163. You can track STARLINK-3306 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
STARLINK-3306 was launched on 2021-12-18 from Vandenberg Space Force Base, United States, primarily used for polar and sun-synchronous orbit launches due to its southward ocean trajectory from California. At its current altitude, the estimated remaining orbital lifetime is: weeks to months. View the full satellite launch log.
Yes — Orbital Radar tracks STARLINK-3306 (NORAD ID 50163) using the latest TLE (two-line element set) orbital data in its live tracking catalogue (see our data sources). Open the live tracker to see its current position, altitude, speed and orbital path updated in real time. You can also browse the satellite directory to find other tracked objects.
STARLINK-3306 travels at approximately 28,030 km/h (17,417 mph) — roughly 7.79 km/s. It completes 16.41 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 33 sunrises and sunsets every 24 hours.
STARLINK-3306 is a member of the Starlink constellation. Satellites in this group work together to provide coordinated coverage, typically in similar orbital planes at comparable altitudes. You can view all Starlink satellites on Orbital Radar’s live tracker.
