STARLINK-4387 — Live Satellite Tracking (NORAD 53490)
Track STARLINK-4387 (NORAD catalog number 53490) 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 is object AB of 2022's 99th orbital launch (COSPAR designation 2022-099AB). It went up together with 36 other satellites from that launch still in the active catalog.
Moving at about 7.72 km/s, STARLINK-4387 flies in low Earth orbit at an altitude of roughly 310 × 311 km, completing one revolution every 90.6 minutes — about 15.9 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0001). Inclined 97.6° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 28.3°. Earth's equatorial bulge drifts that plane eastward about 1.12° per day.

About the Starlink group
STARLINK-4387 is one of 10,703 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-4387 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-4387 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 are available on this page once you select the satellite and share your position for when it is above your horizon and sunlit.
