Image: The integrated Cheops satellite Cheops, the Characterising Exoplanet Satellite, will make observations of exoplanet-hosting stars to measure small changes in their brightness due to the transit of a planet across the star's disc. The information will enable precise measurements of the sizes of the orbiting planets, in particular in the Earth-to-Neptune mass range: combined with measurements of the planet masses, this will provide an estimate of their mean density – a first step to characterising planets outside our Solar System.   More
