The transit method

This is an indirect method for detecting exoplanets. It consists of observing the apparent variation of a star’s light intensity when one of its planets passes between it and an observer. On the basis of calculating this variation, it is possible to gain a whole series of information about the exoplanet: its size, mass, orbit, composition, etc. Read also the article Voyage to the Centre of the Stars.
