STARLINK-1577 — Live Satellite Tracking (NORAD 46063)
Track STARLINK-1577 (NORAD catalog number 46063) 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 AN of 2020's 55th orbital launch (COSPAR designation 2020-055AN). It went up together with 33 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 33,680 revolutions of Earth.
Moving at about 7.63 km/s, STARLINK-1577 flies in low Earth orbit at an altitude of roughly 477 × 479 km, completing one revolution every 94.0 minutes — about 15.3 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 351.5°. Earth's equatorial bulge drifts that plane westward about 4.66° per day.

About the Starlink group
STARLINK-1577 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-1577 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-1577 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.
