STARLINK-1591 — Live Satellite Tracking (NORAD 46045)
Track STARLINK-1591 (NORAD catalog number 46045) 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 U of 2020's 55th orbital launch (COSPAR designation 2020-055U). It went up together with 33 other satellites from that launch still in the active catalog.
Moving at about 7.65 km/s, STARLINK-1591 flies in low Earth orbit at an altitude of roughly 449 × 451 km, completing one revolution every 93.4 minutes — about 15.4 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0001). Inclined 53.2° to the equator, it overflies every latitude up to about 53° north and south. Its orbital plane crosses the equator northbound at right ascension 157.1°. Earth's equatorial bulge drifts that plane westward about 4.72° per day.

About the Starlink group
STARLINK-1591 is one of 11,148 SpaceX Starlink broadband satellites in the current WatchSat catalog — the largest satellite constellation ever flown. Its satellites fly in low-Earth-orbit shells, at a median altitude of about 470 km in this catalog. See the whole Starlink constellation move live in 3D.
Can you see STARLINK-1591 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-1591 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 the “When can I see it?” panel in the live view for when it is above your horizon and sunlit.
