IRIDIUM 124 — Live Satellite Tracking (NORAD 42810)

Track IRIDIUM 124 (NORAD catalog number 42810) 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 H of 2017's 39th orbital launch (COSPAR designation 2017-039H). It went up together with 9 other satellites from that launch still in the active catalog. As of this element set it had completed roughly 48,691 revolutions of Earth.

Moving at about 7.48 km/s, IRIDIUM 124 flies in low Earth orbit at an altitude of roughly 753 × 757 km, completing one revolution every 99.8 minutes — about 14.4 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0002). Inclined 86.4° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 256.1°. Earth's equatorial bulge drifts that plane westward about 0.42° per day.

About the Other Active Satellites group

IRIDIUM 124 is one of 80 Iridium NEXT satellites in the WatchSat catalog. The constellation flies near-polar orbits around 780 km, inclined about 86°, providing global voice and data coverage. Browse all other active satellites live in 3D.

Can you see IRIDIUM 124 from the ground?

Sometimes. Like most low-Earth-orbit spacecraft, IRIDIUM 124 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.
