PLATO (PLAnetary Transits and Oscillations of stars) Observatory will be launched using a "Soyuz" rocket from Kuru space center (South America), it is planned to be brought to the so-called Lagrange point (L2). The initial research program is counted on 6 years.
PLATO will observe the stars, tracking weak but regular decrease in their brightness, indicating that the star’s planet passes in front of it. The observatory will follow about a million stars using 34 telescopes and cameras. It will also investigate the seismic activity of stars with exoplanets and record their mass, radius and age. PLATO observation together with ground-based measurements of the Doppler shift of the spectrum of exoplanets – changes of the wavelengths due to the movement relative to the Earth - will allow to calculate the masses and dimensions of exoplanets and their density, which will give an opportunity to judge their composition.
