Planetary classification is a scheme for classifying planets according to their physical characteristics. This scheme is split into several subclassifications: mass, orbit, surface, and composition. The mass classification includes super-Earth, sub-Earth, sub-Jupiter and super-Jupiter. The orbit classification includes hermian orbit, gaian orbit, martian orbit and jovian orbit. The surface classification includes desert planet, ocean planet and forest planet. The composition classification includes sulfur planet, carbon planet and water planet.
