Fictional info (?)
Suggested nameRyutsu Bugyu
Planet typeCold planet
Ryutsu Bugyu has been known to astronomers since the medieval. This cold planet is named after the deity Ryutsu Bugyu, the god of nature.

The atmospheric pressure at the planet's surface is 60 bar, or roughly the pressure found 945 m under the oceans of Myomyu Kyu. It may have had water oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

The smooth Borealis basin in the northern hemisphere covers 20 percent of the planet and may be a giant impact feature.
