How many earth-like planets orbit the habitable zone of solar-like stars? How planets form and evolve in their planetary systems? What about the interaction with their stars? These are among the questions the ESA PLATO mission is called to answer, through exquisite measurements of exoPLAnet Transits and Oscillations of stars (you now know the origin of the PLATO acronym). The “transit” measurements yield information on the size of the planets, while the “stellar oscillations” give us the mass and age of the stars, which in turn are fundamental to assess the mass and age of the hosted planets. The exquisite quality of all such measurements is secured by 26 ultra large field-of-view cameras that make the eyes of the PLATO mission.
