STARLINK-2015 — Live Satellite Tracking (NORAD 47638)
Track STARLINK-2015 (NORAD catalog number 47638) 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 2021's 12th orbital launch (COSPAR designation 2021-012U). It went up together with 8 other satellites from that launch still in the active catalog.
Moving at about 7.67 km/s, STARLINK-2015 flies in low Earth orbit at an altitude of roughly 408 × 411 km, completing one revolution every 92.6 minutes — about 15.5 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0002). 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 316.3°. Earth's equatorial bulge drifts that plane westward about 4.82° per day.

About the Starlink group
STARLINK-2015 is one of 11,159 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-2015 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-2015 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.
