Planet Type

(methods of classifying planets)

A number of short phrases have come into use to describe various Extra Solar Planets that could be termed Planet Types. The planets Earth, Jupiter, and Neptune are often used to designate the size as are Super-Earth and Mega-Earth, the latter two which may simply designate the size or may also suggest it is rocky.

The adjectives hot and warm are added to designate a planet closer to the star than its Habitable Zone (HZ), e.g., a planet with a week-long orbit around a Sun-like star.

The terms gas planet, liquid planet, and rocky planet are used to designate its primary constituents.
