Suggested nameProio
Planet typeCold planet
Proio and Arapros are cold planets rich in ice. It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 70°K (-203°C), and has a complex, layered cloud structure with ammonia thought to make up the lowest clouds, and hydrogen peroxide the uppermost layer of clouds. This cold planet is named after the deity Proio, the creator of the sky.

At this time it may appear as a bright star-like object, but is often far more difficult to observe than Arapros.
