Suggested nameCepaga'teusbest
Planet typeCold gas giant
It is the coldest planetary atmosphere in its solar system, with a minimum temperature of 88°K (-185°C), and has a complex, layered cloud structure with oxygen thought to make up the lowest clouds, and hydrogen peroxide the uppermost layer of clouds. The planet telescopically displays the complete range of phases, similar to Venus and the Moon, as it moves in its inner orbit relative to 54 Psc, which reoccurs over the so-called synodic period approximately every 70 days.

The hydrogen has probably photodissociated, and the free hydrogen peroxide has been swept into interplanetary space by the solar wind because of the lack of a planetary magnetic field.
