UFO 9 (USA 140)

UFO 9 (USA 140) is an active satellite operated by United States, launched on 1998-10-20 from Cape Canaveral, Florida. With over 28 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Geostationary Orbit (GEO) at altitudes between 36,334 km and 36,435 km with an inclination of 11.3°. It travels at approximately 10,992 km/h (3.05 km/s), completing one full orbit every 24.4 hours — that’s roughly 0.98 orbits per day. At geostationary altitude, there is no meaningful atmospheric drag — this object will remain in orbit indefinitely unless actively deorbited. Orbital Radar tracks UFO 9 (USA 140) in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

UFO 9 (USA 140) occupies geostationary orbit at approximately 35,786 km above the equator, where its orbital period matches the Earth’s 24-hour rotation. From the ground, it appears to hover over a fixed point — ideal for broadcast television, weather monitoring and wideband communications. With an inclination of 11.3°, it traces a small figure-of-eight pattern relative to the equator rather than remaining perfectly stationary, which can indicate aging stationkeeping fuel or a deliberate inclined-orbit strategy. Within ±50 km of UFO 9 (USA 140)’s average altitude, there are currently 25 active payloads and 15 tracked debris or rocket body fragments. United States operates approximately 12,339 active satellites in total, of which 4 share a similar altitude band with UFO 9 (USA 140).
