Fictional info (?)
Suggested nameKyomyo Na
Planet typeLarge cold gas giant
The atmospheric pressure at the planet's surface is 0.0011 bar, or roughly the pressure found 585 m under the oceans of Earth. It may have had methane oceans in the past, but these would have vaporized as the temperature rose due to a runaway greenhouse effect.

The inhospitable surface is mostly crowded with unreliable medieval plants called the "Noryo Beibya". They feed alone by devouring a substance called "Mihepya". The Noryo Beibya are not related to the Mifu Nyuhya but with scales and vary in length from 16 to 33 cm. Most Noryo Beibya are able to thrive at temperatures from 140 to 180°C and even the acidic environment.
