Fictional info (?)
Suggested nameJopyura
Planet typeCold planet
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 68°K (-205°C), and has a complex, layered cloud structure with ammonium hydrosulfide (NH4SH) thought to make up the lowest clouds, and carbonyl sulfide the uppermost layer of clouds.

The polar regions are constantly below 99°K (-174°C).

The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries.
