Planet Classification Ice Giant

Kleistos is the 4th planet of Lampardion, and the largest planet in terms of volume, and 2nd in terms of mass.

It is an ice giant, with a large amount of hydrogen and helium, but also a surprisingly high concentration of water in the atmosphere. Its mantle consists primarily of solid water, ammonia, methane, and other hydrocarbon ices, which surrounds the hot iron core.

Biology Edit

As an ice giant, Kleistos has no life on what could be construed as its surface.
