Impression of the exoplanet Kepler 90h seen from the surface of one of its moons. Kepler 90h is one of seven planets known to orbit the G-type star Kepler 90. It is likely a gas planet. Its mass and radius are very similar to Jupiter??? but it is rather warmer with an average temperature of around 19 Celsius. It orbits its star within the habitable zone ??where liquid water is possible of the surface of a planet under ideal conditions - in 332 days at almost exactly the same distance that the Earth goes around the Sun, one astronomical unit. In this scene the planet is imagined with a set of Saturn-like rings, seen from the surface of a rocky moon with a substantial atmosphere.
