Abstract
CHEOPS (Characterizing ExoPlanet Satellite) is a Swiss led ESA mission to perform high precision exoplanet transit photometry from an earth orbiting satellite. The CHEOPS satellite will be built by a consortium of European contributors under lead of the University of Bern, and shall fit into a very low cost mission framework. As the first ESA S-class mission, CHEOPS is expected to launch in 2017.

We will review the motivation for CHEOPS science and the design of the instrument and mission. CHEOPS will perform ultra-high precision photometric monitoring of selected bright target stars almost anywhere on the sky with sufficient precision to detect Earth sized transits. It will also be able to detect transits of RV-planets by photometric monitoring if the geometric configuration results in a transit. CHEOPS follow-up observations will provide valuable data for constraining the mass-radius relation of exoplanets, especially in the Neptune mass regime. During the planned 3.5 year mission, it is expected that more than 500 targets will be observed.
