Planetary Geology (also called as Exogeology or Astrogeology) is a branch of Planetary Science that deals with the Geology of celestial bodies like planets and their moons, asteroids, meteorites, comets etc. The subject involves the application of Earth's Geological features to interpret the Geology of celestial bodies. The internal structure, chemical composition, surface features like craters, fluvial processes etc are studied.

The data is collected from images and meteorites. Although the concepts of General Geology are applicable to Planetary Geology too, a lot of new terms are used to indicate features. The nomenclature is based on the standards of International Astronomical Union to provide unique description for specific features.
