STARLINK-3105 — Live Satellite Tracking (NORAD 49440)
Track STARLINK-3105 (NORAD catalog number 49440) 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 AJ of 2021's 104th orbital launch (COSPAR designation 2021-104AJ). It went up together with 46 other satellites from that launch still in the active catalog.
Moving at about 7.61 km/s, STARLINK-3105 flies in low Earth orbit at an altitude of roughly 507 × 508 km, completing one revolution every 94.6 minutes — about 15.2 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 112.5°. Earth's equatorial bulge drifts that plane westward about 4.59° per day.

About the Starlink group
STARLINK-3105 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-3105 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-3105 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.
