📖 About This Object
ECHOSTAR 21 is an active satellite operated by Echostar Satellite Services, LLC (United States), launched on 2017-06-08 from Baikonur, Kazakhstan. It orbits in Geostationary Orbit (GEO) at altitudes between 35,778 km and 35,796 km with an inclination of 1.8°. 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 ECHOSTAR 21 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
ECHOSTAR 21 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 1.8°, 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 ECHOSTAR 21’s average altitude, there are currently 713 active payloads and 58 tracked debris or rocket body fragments — notable neighbours include ASTRA 1N, GOES 16, TDRS 13. United States operates approximately 12,339 active satellites in total, of which 146 share a similar altitude band with ECHOSTAR 21.
❓ Frequently Asked Questions
ECHOSTAR 21 orbits at approximately 35,787 km altitude, where the orbital period matches the Earth’s 24-hour rotation. This means it stays above the same point on the equator at all times. Its actual speed is still 11,070 km/h — it just keeps pace with the ground below. With an inclination of 1.8°, it actually traces a small figure-of-eight pattern rather than remaining perfectly fixed. Learn more about geostationary orbits.

Yes — Orbital Radar tracks ECHOSTAR 21 (NORAD ID 42749) using the latest TLE (two-line element set) data from Space-Track and CelesTrak. Open the live tracker to see its current position, altitude, speed and orbital path updated in real time. You can also browse the satellite directory to find other tracked objects.
ECHOSTAR 21 travels at approximately 11,070 km/h (6,878 mph) — roughly 3.07 km/s. Despite this high speed, it appears stationary from the ground because it matches the Earth’s rotation. Geostationary satellites are actually slower than LEO satellites because orbital velocity decreases with altitude.
