A government satellite, CHEOPS is operated by European Space Agency (ESA) of ESA for the purpose of space science.
Delivered via Soyuz (launch vehicle) from Guiana Space Center, it was launched into space on 18 December 2019 and orbits the Earth as a sun-synchronous LEO satellite. CHEOPS was constructed by European Space Agency (ESA/EADS CASA Espacio).
Designed with an operational lifetime of 5 years, CHEOPS has a launch mass of 273 kg and navigates with the COSPAR ID 2019-092B and NORAD ID 44874.
With an orbital eccentricity of 7.78E-04, the satellite's perigee, which is the point of the orbit closest to the Earth's center of mass, is 697km while its apogee, which is the point of the orbit farthest from the Earth's center of mass, is 708km. It takes 99 minutes to orbit the Earth at an inclination of 98 degrees to the equatorial plane of the Earth.
