    • Description

      This animation shows a planet whose orbit is aligned in such a way that it crosses the disc of its parent star as seen from Earth: during these transits, the star appears less bright. By detecting these periodic decreases of brightness over time, it is possible to detect the presence of the planet orbiting the star.
