Suijin

Suijin is a planet orbiting the star Beta Hydri.

Characteristics
Suijin weighs in at 6.6 times the mass of Earth, orbiting around Beta Hydri at a distance similar to that of Earth. The most widely accepted hypothesis states that Suijin was once a massive, more watery earthlike world, but has since become a panthalassic world, covered in a fervid global ocean hundreds of miles deep in places, created by extensive melting of ices as Beta Hydri grew older and brighter and began evolving off the main sequence in its entirety.

The deep blue oceanic surface of Suijin is hard to discern under its immensely thick and cloudy atmosphere, and the planet appears strikingly white from a distance, shining four times brighter than Venus in the night skies of any nearby worlds. Despite the immense mass of the world, Suijin's ocean is slowly evaporating, and the planet will be reduced to a rocky husk in one billion years.
