COSMOS 2451 — Live Satellite Tracking (NORAD 35498)
Track COSMOS 2451 (NORAD catalog number 35498) 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 2009, launched on the 36th orbital launch of that year (COSPAR designation 2009-036A). It went up together with 1 other satellite from that launch still in the active catalog. As of this element set it had completed roughly 77,782 revolutions of Earth.
Moving at about 7.12 km/s, COSMOS 2451 flies in low Earth orbit at an altitude of roughly 1,504 × 1,516 km, completing one revolution every 116.0 minutes — about 12.4 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0007). Inclined 82.5° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 41.4°. Earth's equatorial bulge drifts that plane westward about 0.62° per day.

About the Other Active Satellites group
COSMOS 2451 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 COSMOS 2451 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, COSMOS 2451 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.
