COSMOS 2439 — Live Satellite Tracking (NORAD 32956)
Track COSMOS 2439 (NORAD catalog number 32956) 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 D of 2008's 25th orbital launch (COSPAR designation 2008-025D). 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 82,991 revolutions of Earth.
Moving at about 7.13 km/s, COSMOS 2439 flies in low Earth orbit at an altitude of roughly 1,484 × 1,518 km, completing one revolution every 115.8 minutes — about 12.4 trips around Earth per day. The orbit is essentially circular (eccentricity 0.0022). Inclined 82.5° — nearly pole-to-pole — its ground track sweeps essentially every latitude. Its orbital plane crosses the equator northbound at right ascension 306.8°. Earth's equatorial bulge drifts that plane westward about 0.62° per day.

About the Other Active Satellites group
COSMOS 2439 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 2439 from the ground?
Sometimes. Like most low-Earth-orbit spacecraft, COSMOS 2439 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.
