Cheops ESA Satellite

Cheops is ESAs CHaracterising ExOPlanet Satellite. It is the first space mission dedicated to studying bright, nearby stars that are already known to host exoplanets, in order to make high-precision observations of the planets size as it passes in front of its host star. It focuses on planets in the super-Earth to Neptune size range, with its data enabling the bulk density of the planets to be derived - a first-step characterisation towards understanding these alien worlds.
