📖 About This Object
STARLINK-6039 is an active satellite operated by SpaceX (United States), launched on 2023-04-27 from Vandenberg SFB, California. It orbits in Low Earth Orbit (LEO) at altitudes between 547 km and 552 km with an inclination of 97.3°. It travels at approximately 27,321 km/h (7.59 km/s), completing one full orbit every 96 minutes — that’s roughly 15.06 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. It is part of the Starlink constellation group. At its current altitude, the estimated orbital lifetime before atmospheric re-entry is ~3–10 years. Orbital Radar tracks STARLINK-6039 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-6039 orbits at an average altitude of 550 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 STARLINK-6039’s average altitude, there are currently 3,457 active payloads and 360 tracked debris or rocket body fragments — notable neighbours include STARLINK-1184, STARLINK-1276, ONEWEB-0050. This makes it one of the more crowded altitude bands, containing roughly 19.9% of all active satellites. With an inclination of 97.3°, STARLINK-6039 passes over latitudes between 97.3°N and 97.3°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 12,339 active satellites in total, of which 2,814 share a similar altitude band with STARLINK-6039.
🔗 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-6039 is in a sun-synchronous orbit (SSO), a specialised form of LEO at approximately 550 km altitude. Its 97.3° inclination causes the orbital plane to precess at exactly the rate of the Earth’s revolution around the Sun, so the satellite crosses each latitude at a consistent local solar time. It completes one orbit every 96 minutes, travelling at 27,321 km/h.
STARLINK-6039 is operated by SpaceX (United States). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 56319. You can track STARLINK-6039 in real time on Orbital Radar’s live tracker or browse all operators in the operator directory.
STARLINK-6039 was launched on 2023-04-27 from Vandenberg SFB, California, 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: ~3–10 years. View the full satellite launch log.
Yes — Orbital Radar tracks STARLINK-6039 (NORAD ID 56319) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. 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-6039 travels at approximately 27,321 km/h (16,977 mph) — roughly 7.59 km/s. It completes 15.06 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 30 sunrises and sunsets every 24 hours.
STARLINK-6039 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.
