CHEOPS satellite 3D model in space

The CHaracterizing ExoPlanets Satellite (CHEOPS) is a proposed ESA Small Mission. CHEOPS will be the first mission dedicated to search for transits by means of ultrahigh precision photometry on bright stars already known to host planets. By being able to point at nearly any location on the sky, it will provide the unique capability of determining accurate radii for a subset of those planets for which the mass has already been estimated from ground-based spectroscopic surveys. It will also provide precision radii for new planets discovered by the next generation ground-based transits surveys (Neptune-size and smaller).

The mission is proposed by a consortium led by Prof. Benz and Dr. Broeg at the University of Bern, with participating institutes in Austria, Belgium, France, Italy, Sweden, Switzerland and the United Kingdom.
