Terrestrial planet hunter
ESA’s mission Plato, PLAnetary Transits and Oscillations of stars, will use its 26 cameras to study terrestrial exoplanets in orbits up to the habitable zone of Sun-like stars. The mission will measure the sizes of exoplanets and discover exomoons and rings around them. Plato will also characterise planets' host stars by studying tiny light variations in the starlight it receives.
