Fictional info (?)
Suggested nameKadora Elmesut
Planet typeHuge hot gas giant
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 63°K (-210°C), and has a complex, layered cloud structure with ammonium hydrosulfide (NH4SH) thought to make up the lowest clouds, and hydrogen peroxide the uppermost layer of clouds.

The nitric oxide has probably photodissociated, and the free hydrogen peroxide has been swept into interplanetary space by the solar wind because of the lack of a hydrogen layer.

The volume of water detected has been estimated to be equivalent to the volume of water in Lake Superior.
