Planetary geology, alternatively known as astrogeology or exogeology, is a planetary science discipline concerned with the geology
of the celestial bodies such as the planets and their moons, asteroids, comets, and meteorites. Although the geo- prefix typically indicates topics of or relating to Earth, planetary geology
is named as such for historical and convenience reasons; due to the types of investigations involved, it is closely linked with Earth-based geology.
includes such topics as determining the internal structure of the terrestrial planets, and also looks at planetary volcanism and surface processes such as impact craters, fluvial and aeolian processes. The structures of the giant planets and their moons are also examined, as is the make-up of the minor bodies of the Solar System, such as asteroids, the Kuiper Belt, and comets. Several tools are used in planetary geology, including common archaeological tools such as hammers, shovels, brushes, etc. are often used by planetary geologists. Along with these common tools, new advanced technologies are used by planetary geologists  Scientists also with these tools, use maps and images that telescopes on Earth (thirty meter telescope) and orbiting telescopes (Hubble) have taken different planetary bodies.  The maps and images are stored in the NASA Planetary Data System where tools such as the Planetary Image Atlas help to search for certain items such as geological features including: mountains, ravines, and craters.
