Kepler-47

Kepler-47 is a binary star system with two planets in orbit around the pair of stars located about 5,000 light-years away from Sol. The two planets are designated Kepler-47b, and Kepler-47c. Kepler-47 was the first circumbinary multi-planet system discovered by NASA's Kepler mission. The outermost of the planets is a gas giant orbiting within the habitable zone of the stars. Because most stars are binary, the discovery that multi-planet systems could form in such a system heavily impacted Terran theories of planetary formation.

Reached by UE explorers in 2186 OTT, Kepler-47c was found to be a superjovian planet. Kepler-47b is a rocky planet that has a methane atmosphere.
