CHEOPS

NSSDCA ID: 2019-092B
COSPAR ID: 2019-092A

Description

CHEOPS (CHaracterising ExOPlanets Satellite) is a planned European space telescope for the study of the formation of extrasolar planets. The main goal of CHEOPS will be to accurately measure the radii of the exoplanets for which ground-based spectroscopic surveys have already provided mass estimates. Knowing both the mass and the size of the exoplanets will allow scientists to determine the planets' density and thus their approximate composition, such as whether they are gaseous or rocky. CHEOPS will be the most efficient instrument to search for shallow transits and to determine accurate radii for known exoplanets in the super-Earth to Neptune mass range (1-6 Earth radius).
