Planetary geology is a planetary science discipline concerned with the geology of the celestial bodies such as the planets and their moons, asteroids, comets, and meteorites. Alternatively known as astrogeology or exogeology.

Eugene Shoemaker is credited with inventing the Branch of Astrogeology (now called the Astrogeology Research Program) within the U.S. Geological Survey. He made important contributions to the field and the study of impact craters, lunar science, asteroids, and comets.

The Visitor Center at Barringer Meteor Crater near Winslow, Arizona includes a Museum of Astrogeology.
