📖 About This Object
MOLNIYA 1-40 is an active satellite operated by Russia (CIS), launched on 1978-06-02 from PKMTR. With over 48 years in orbit, it has far exceeded many satellites’ design lifetimes. It orbits in Medium Earth Orbit (MEO) at altitudes between 2,112 km and 38,250 km with an inclination of 64.0°. It travels at approximately 13,948 km/h (3.87 km/s), completing one full orbit every 11 hours 58 minutes — that’s roughly 2.01 orbits per day. Its orbital eccentricity of 0.6805 gives it a noticeably elliptical path, with significant altitude variation between perigee and apogee. It is part of the Geo Protected Plus constellation group. Orbital Radar tracks MOLNIYA 1-40 in real time using the latest two-line element set (TLE) data, providing live position, altitude, speed and orbital path updated continuously.
🌍 Orbit Context
MOLNIYA 1-40 operates in Medium Earth Orbit (MEO), the region between LEO and GEO spanning roughly 2,000 to 35,786 km altitude. MEO is home to navigation constellations (GPS at ~20,200 km, Galileo at ~23,222 km, GLONASS at ~19,130 km) and some communications systems. The higher altitude gives each satellite a much larger ground footprint than LEO, meaning fewer satellites are needed for global coverage, but signal latency is higher and radiation exposure — particularly from the Van Allen belts — is a significant design challenge.
MOLNIYA 1-40 orbits in Medium Earth Orbit (MEO) at altitudes between 2,112 km (perigee) and 38,250 km (apogee), with an average altitude of approximately 20,181 km. It completes one orbit every 11 hours 58 minutes, travelling at approximately 13,948 km/h (8,667 mph).
MOLNIYA 1-40 is operated by Russia (CIS). It is catalogued by the U.S. Space Surveillance Network under NORAD ID 10925. You can track MOLNIYA 1-40 in real time on Orbital Radar’s live tracker.

Yes — Orbital Radar tracks MOLNIYA 1-40 (NORAD ID 10925) 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.
MOLNIYA 1-40 travels at approximately 13,948 km/h (8,667 mph) — roughly 3.87 km/s. It completes 2.01 orbits per day, meaning the crew or instruments aboard (if any) would experience approximately 4 sunrises and sunsets every 24 hours.
MOLNIYA 1-40 is a member of the Geo Protected Plus constellation. Satellites in this group work together to provide coordinated coverage, typically in similar orbital planes at comparable altitudes. You can view all Geo Protected Plus satellites on Orbital Radar’s live tracker.
