FENGYUN 3F — Live Satellite Tracking (NORAD 57490)
Track FENGYUN 3F (NORAD catalog number 57490) 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 2023, launched on the 111th orbital launch of that year (COSPAR designation 2023-111A). As of this element set it had completed roughly 16,051 revolutions of Earth.
Moving at about 7.44 km/s, FENGYUN 3F flies in low Earth orbit at an altitude of roughly 832 × 833 km, completing one revolution every 101.4 minutes — about 14.2 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0001). Its 98.7° retrograde, near-polar inclination is characteristic of a Sun-synchronous orbit — the type Earth-imaging and weather satellites use to revisit each spot at the same local solar time. Its orbital plane crosses the equator northbound at right ascension 318.7°. Earth's equatorial bulge precesses that plane eastward about 0.98° per day, matching the Sun's apparent motion — which is what holds its lighting constant.

About the Other Active Satellites group
FENGYUN 3F's name places it among WatchSat's 36 weather and environmental-monitoring satellites — a family that includes the NOAA, GOES, METEOSAT, METOP, FENGYUN, HIMAWARI and DMSP fleets. Browse all other active satellites live in 3D.
Can you see FENGYUN 3F from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, FENGYUN 3F 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.
