TERRA — Visible Passes (NORAD 25994)
Find out when TERRA is visible to the naked eye from your location. Share your position on this page and WatchSat computes the next passes in your browser: the exact rise time, which direction it appears and disappears, how high it climbs, and how long it stays in view. It orbits at roughly 694–699 km with a 99-minute period, inclined 97.9° to the equator.
A pass is visible when the satellite is above your horizon while your sky is dark and the spacecraft is still lit by the Sun — which is why sightings cluster around dawn and dusk. Predictions use the SGP4 orbital model with the latest CelesTrak element sets.
