Fictional info (?)
Suggested nameOphe'mab
Planet typeHot gas giant
Ophe'mab is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the valleys, deserts, and polar ice caps of Earth. Ophe'mab is orbiting WASP-75 every 2.5 Earth days.

It is named after the deity Ophe'mab, the messenger of the underworld.

The atmospheric pressure at the planet's surface is 0.18 bar, or roughly the pressure found 1170 m under the oceans of Creschal Io.

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