STARLINK-4391 — Live Satellite Tracking (NORAD 53189)
Track STARLINK-4391 (NORAD catalog number 53189) live on the WatchSat interactive 3D globe above. Its position is propagated in real time from the latest CelesTrak two-line element set using the SGP4/SDP4 orbital model — the same math professional trackers run. It has been on orbit since 2022, launched on the 84th orbital launch of that year (COSPAR designation 2022-084A). It went up together with 39 other satellites from that launch still in the active catalog.
Moving at about 7.63 km/s, STARLINK-4391 flies in low Earth orbit at an altitude of roughly 483 × 487 km, completing one revolution every 94.2 minutes — about 15.3 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0003). Its 97.3° retrograde, near-polar inclination is characteristic of a Sun-synchronous orbit — the type Earth-imaging and weather satellites use to revisit each spot at the same local solar time. Its orbital plane crosses the equator northbound at right ascension 306.3°. Earth's equatorial bulge precesses that plane eastward about 0.98° per day, matching the Sun's apparent motion — which is what holds its lighting constant.

About the Starlink group
STARLINK-4391 is one of 10,717 SpaceX Starlink broadband satellites in the current WatchSat catalog — the largest satellite constellation ever flown. Starlink operates in low-Earth-orbit shells around 540–570 km. See the whole Starlink constellation move live in 3D.
Can you see STARLINK-4391 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-4391 is visible only around dawn and dusk, when your sky is dark but the satellite is still sunlit — and whether you can spot it depends on its size and reflectivity. See pass predictions for your location for when it is above your horizon and sunlit.
