Planetary science
Planetary science, also known as planetology or planetary astronomy, is the science of planets and the solar system, and incorporates an interdisciplinary approach drawing from diverse sciences. Planetary science may be considered a part of the Earth sciences, or more logically, as its parent field. Research tends to be done by a combination of astronomy, space exploration (particularly unmanned space missions), and comparative, experimental and meteorite work based on Earth. There is also an important theoretical component and considerable use of computer simulation. Planetary science studies objects ranging in size from micrometeoroids to gas giants, their composition, dynamics and history. When the discipline concerns itself with a celestial body in particular, a specialised term is used, as shown in the table below (only Heliology, Earth science, Selenology, and Areology are currently in common use):
