Ice planet

An ice planet is a type of hypothetical exoplanet with an icy surface of volatiles such as water, ammonia, and methane. Ice planets consist of a global cryosphere. They are bigger versions of the minor planets of the Solar System, which includes the icy moons Europa, Enceladus, and Triton, the dwarf planets Pluto and Eris, and many other icy small Solar System bodies such as comets.
