Kepler-1647b (also Kepler-1647 (AB) b or KOI-2939b ) is a Jupiter-sized gas giant orbiting the double star Kepler-1647 (AB) in the constellation Swan , 3,700 light years from Earth . The planet orbits the sun about two big stars zirkumbinär a relatively large distance. It takes 1,107 days to complete one cycle and is in the habitable zone . Its age is estimated to be 4.4 billion years.
Life
Since Kepler-1647b is a gas giant, life as we know it is impossible on Kepler-1647b. However, it lies in the habitable zone and there could be exomonde on which there are living conditions. So far, however, no evidence of such moons has been discovered.
