The Gas Giant Planet Kepler-1625b Clock

Artist's concept of the gas giant planet Kepler-1625b and a suspected accompanying moon. Estimated to be as big as the planet Neptune, the moon is unlike anything found inside our solar system. It might have formed through a different process than known for the solar system's nearly 200 moons. The planet and moon orbit the star Kepler-1625, located 8,000 light-years away in the constellation Cygnus. The parent star is similar to our Sun, and the planet and moon are located in its habitable zone where temperatures allow for liquid water to remain stable. However, both worlds are gaseous bodies and not suitable for life as we know it.
