TIANQI-21 — Live Satellite Tracking (NORAD 57792)
Track TIANQI-21 (NORAD catalog number 57792) 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 135th orbital launch of that year (COSPAR designation 2023-135A). It went up together with 3 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 15,631 revolutions of Earth.
Moving at about 7.45 km/s, TIANQI-21 flies in low Earth orbit at an altitude of roughly 813 × 831 km, completing one revolution every 101.2 minutes — about 14.2 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0013). Inclined 50.0° to the equator, it overflies every latitude up to about 50° north and south. Its orbital plane crosses the equator northbound at right ascension 167.2°. Earth's equatorial bulge drifts that plane westward about 4.21° per day.

Can you see TIANQI-21 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, TIANQI-21 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.
