Fictional info (?)
Suggested nameBrielnus-medora
Planet typeHot planet
Brielnus-medora's atmosphere is similar to Ianyre-harraq's in its primary composition of ethane and hydrogen peroxide, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. It is named after the deity Brielnus-medora, the messenger of destruction.

Having almost no atmosphere to retain heat, it has surface temperatures that vary diurnally more than on any other planet in its solar system, ranging from 70°K (-203°C) at night to 490°K (217°C) during the day across the equatorial regions.

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).
