STARLINK-40083 — Live Satellite Tracking (NORAD 100855)
Track STARLINK-40083 (NORAD catalog number 100855) 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 has been on orbit since 2026, launched on the 225th orbital launch of that year (COSPAR designation 2026-225A). It went up together with 25 other satellites from that launch still in the active catalog.
Moving at about 7.70 km/s, STARLINK-40083 flies in low Earth orbit at an altitude of roughly 353 × 353 km, completing one revolution every 91.4 minutes — about 15.7 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0000). Its 30.5° inclination keeps its ground track over the tropics and lower mid-latitudes. Its orbital plane crosses the equator northbound at right ascension 175.1°. Earth's equatorial bulge drifts that plane westward about 7.14° per day.

About the Starlink group
STARLINK-40083 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-40083 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-40083 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. Newly launched batches are the exception — right after launch they can form a naked-eye Starlink train. Check the launch schedule for what just went up. See the “When can I see it?” panel in the live view for when it is above your horizon and sunlit.
