The PLATO Mission and Its Objectives
The PLATO mission focuses on discovering exoplanets by monitoring 200,000 sun-like stars, using 26 small telescopes that observe the brightness of these stars. This technique involves the transit method, where a planet passing in front of a star causes a slight dip in brightness, making it detectable. The observatory will not only identify planets but also analyze star oscillations, which can help determine the stars' mass and radius, essential for understanding exoplanet properties. Scheduled to operate for at least five years, the satellite will systematically observe its targets, ensuring comprehensive coverage of the stars it studies.
