SDA_1666 — Live Satellite Tracking (NORAD 65976)
Track SDA_1666 (NORAD catalog number 65976) 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 C of 2025's 230th orbital launch (COSPAR designation 2025-230C). It went up together with 20 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 4,511 revolutions of Earth.
Moving at about 7.37 km/s, SDA_1666 flies in low Earth orbit at an altitude of roughly 963 × 965 km, completing one revolution every 104.2 minutes — about 13.8 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0001). Inclined 81.3° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 136.3°. Earth's equatorial bulge drifts that plane westward about 0.92° per day.

Can you see SDA_1666 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, SDA_1666 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.
