About
ETH Zurich designed and built the photometer for ESA CHEOPS (CHaracterising ExOPlanet Satellite), launched in December 2019. The instrument achieves photometric precision of ~20 parts per million, enabling characterization of known exoplanets by measuring their radius through transit observations. ETH Zurich serves as the mission Data Center and contributes to data analysis and mission science.
