Suggested nameHepolythel Kin
Planet typeSmall warm gas planet
Its orbital period around WASP-47 of 9 earth days is the shortest of all the planets in its solar system.

The atmospheric pressure at the planet's surface is 0.5 bar, or roughly the pressure found 675 m under the oceans of Earth. It may have had ethane oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

The two polar ice caps appear to be made largely of sand.
