Summary[edit]

Description
English: Artist's impression of Kepler-22 b sunset (small zoom-in) over some of its islands. Kepler-22 b is a warm super-Earth which may be covered by ocean. An ocean planet is a type of planet that contains a substantial amount of water in the form of oceans, potentially submerging even all dry land. Earth is an ocean world with a surface ocean, which forms 75% of Earth's surface and is spread out globally.

Kepler-22 b’s true nature isn't well known; at 2.4 times Earth’s radius, it might even be gaseous. But theoretically an ocean world tipped on its side – a bit like our Solar System’s ice giant, Uranus – turns out to be comfortably habitable world. An exoplanet in Earth’s size range, at a comparable distance from its star and covered in water, could have an average surface temperature of about 15.5 °C. Because of its radical tilt, its north and south poles would be alternately bathed in sunlight and darkness, for half a year each, as the planet circled its star. This is not an artificial intelligence (AI) work.
