Kepler-1625b is an extrasolar planet (exoplanet) orbiting the yellow star Kepler-1625 about 4,000 light-years away. A large gas giant, it is between 5.9 and 11.67 times the size of Earth and orbits every 287.4 days.[1] This places it within or near the system's habitable zone, depending on the exact size of the star. In 2017, evidence for a Neptune-sized exomoon orbiting at a distance of 0.0023 AU was announced.[2][3]
