Suggested nameProsteph'noe
Planet typeHot planet
This hot planet is named after the deity Prosteph'noe, the messenger of fear.

Prosteph'noe's surface appears partially bruised and is similar in appearance to the Moon's, indicating that it has been geologically inactive for billions of years.

Prosteph'noe's surface is a arid desertscape interspersed with slab-like rocks and is periodically resurfaced by volcanism.

The smooth Borealis basin in the northern hemisphere covers 23 percent of the planet and may be a giant impact feature. Two of Prosteph'noe's moons, Medeiato Pemedelia and Onepoly-kelene, are are slightly unusually shaped.

Future targets for exploration in the Prosteph'noe system include the probable ice-covered liquid ocean of its moon Onepoly-kelene.
