Kepler-34b (formally Kepler-34(AB)b) is a circumbinary planet announced with Kepler-35b. It is a small gas giant that orbits every ~288 days around two stars. Despite the planet's relatively long orbital period, its existence could be confirmed quickly due to transiting both of its host stars.
Kepler-34b was unlikely to form at its current orbit, and likely migrated early from its birth orbit beyond 1.5
