STARLINK-1321 — Live Satellite Tracking (NORAD 45573)

Track STARLINK-1321 (NORAD catalog number 45573) 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 AU of 2020's 25th orbital launch (COSPAR designation 2020-025AU). It went up together with 18 other satellites from that launch still in the active catalog.

Moving at about 7.73 km/s, STARLINK-1321 flies in low Earth orbit at an altitude of roughly 306 × 309 km, completing one revolution every 90.5 minutes — about 15.9 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0003). Inclined 53.0° to the equator, it overflies every latitude up to about 53° north and south. Its orbital plane crosses the equator northbound at right ascension 24.8°. Earth's equatorial bulge drifts that plane westward about 5.10° per day.

About the Starlink group

STARLINK-1321 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-1321 from the ground?

Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-1321 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.
