Cheops: how to build a planet-watcher model

Print out and build a paper model of Cheops, the CHaracterising ExOPlanet Satellite, a space science mission to study known exoplanets orbiting bright, nearby stars.

Cheops will measure accurate sizes of Earth- to Neptune-sized planets. By combining this information with existing mass measurements, it will be possible to establish the bulk density and to put constraints on the composition of these planets. It is a Small-class mission in ESA’s Science programme in partnership with Switzerland, with important contributions from other ESA member states.

Building the model requires scissors and glue. Remember to take into account ample time to cut out all the pieces.
