STARLETTE — Live Satellite Tracking (NORAD 7646)
Track STARLETTE (NORAD catalog number 7646) 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 1975, launched on the 10th orbital launch of that year (COSPAR designation 1975-010A).
Its speed swings from 7.22 km/s at apogee to 7.53 km/s at perigee. STARLETTE flies in low Earth orbit at an altitude of roughly 812 × 1,114 km, completing one revolution every 104.2 minutes — about 13.8 trips around Earth per day. The orbit is mildly elliptical (eccentricity 0.0206), so its altitude varies between 812 km and 1,114 km over each revolution. Inclined 49.8° to the equator, it overflies every latitude up to about 50° north and south. Its orbital plane crosses the equator northbound at right ascension 140.8°. Earth's equatorial bulge drifts that plane westward about 3.95° per day.

About the Other Active Satellites group
STARLETTE is one of 4,471 active satellites in WatchSat's general catalog — the broad population of Earth-observation, communications, science, amateur-radio and technology spacecraft outside the giant broadband constellations. Browse all other active satellites live in 3D.
Can you see STARLETTE from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, STARLETTE 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.
