STARLINK-35881 — Live Satellite Tracking (NORAD 66830)
Track STARLINK-35881 (NORAD catalog number 66830) 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 K of 2025's 280th orbital launch (COSPAR designation 2025-280K). It went up together with 26 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 4,986 revolutions of Earth.
Moving at about 7.59 km/s, STARLINK-35881 flies in low Earth orbit at an altitude of roughly 549 × 553 km, completing one revolution every 95.5 minutes — about 15.1 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0003). Inclined 70.0° to the equator, it overflies every latitude up to about 70° north and south. Its orbital plane crosses the equator northbound at right ascension 125.7°. Earth's equatorial bulge drifts that plane westward about 2.56° per day.

About the Starlink group
STARLINK-35881 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-35881 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLINK-35881 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.
