Fictional info (?)
Suggested nameGyaku-pihone
Planet typePlanet
It may have had oxygen oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

Because of its fast rotation, the planet's shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator).
