Two Planets of Kepler-47

The two planets of Kepler-47, the first transiting circumbinary system -- a system with more than one planet orbiting a pair of stars. Kepler-47b, on the right, has three times the radius of earth and orbits the pair of stars in less than 50 days while Kepler-47c is thought to be a gaseous giant, slightly larger than Neptune with an orbital period of 303 days.
