STAR ONE C2

STAR ONE C2 is an active satellite operated by Embratel Star One (Brazil), launched on 2008-04-18 from Guiana Space Centre, Kourou. After 18 years in orbit, it continues to be tracked by global surveillance networks. It orbits in Geostationary Orbit (GEO) at altitudes between 35,776 km and 35,797 km with an inclination of 1.3°. It travels at approximately 11,070 km/h (3.07 km/s), completing one full orbit every ~24 hours (geosynchronous) — that’s roughly 1.00 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 STAR ONE C2 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.

STAR ONE C2 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 1.3°, 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 STAR ONE C2’s average altitude, there are currently 713 active payloads and 59 tracked debris or rocket body fragments — notable neighbours include ASTRA 1N, GOES 16, TDRS 13. Brazil operates approximately 31 active satellites in total, of which 11 share a similar altitude band with STAR ONE C2.
