Kepler-47c (also known as Kepler-47(AB)-c and by its Kepler Object of Interest designation KOI-3154.02) is an exoplanet orbiting the binary star system Kepler-47, the outermost of three such planets discovered by NASA's Kepler spacecraft. The system, also involving two other exoplanets, is located about 3,400 light-years (1,060 parsecs) away.
