Kepler-90g edit
Kepler-90 g is a clear jovian or water cloud jovian orbiting the star Kepler-90, located in the constellation Draco. The planet type is uncertain because its temperature is 340°K, on the border of being a clear or water cloud jovian. Its radius is 72.3% that of Jupiter. It is 0.71 AU from the star that it is orbiting, Kepler-90.

It was discovered by the Kepler telescope in October 2013. It orbits its parent star at only 0.71 astronomical units away, and at its distance it completes an orbit once every 210.60697 days. The orbit of the planet is perturbed and its orbital period changes by 25.7 hours between two transits in a row during the length of the observations, which is the largest perturbation in the system.[1]
