[[Planetary science]] or planetology, is the scientific study of planets, which include [[terrestrial planets]] like the Earth, and other types of planets, such as [[gas giants]] and [[ice giant]]s. Planetary science also concerns other celestial bodies, such as [[dwarf planet]]s [[moons]], [[asteroids]], and [[comets]]. This largely includes the [[Solar System]], but recently has started to expand to [[exoplanets]], particularly terrestrial [[exoplanets]]. It explores various objects, spanning from micrometeoroids to gas giants, to establish their composition, movements, genesis, interrelation, and past. Planetary science is an interdisciplinary domain, having originated from [[astronomy]] and [[Earth science]], and currently encompassing a multitude of areas, such as [[planetary geology]], [[cosmochemistry]], [[atmospheric science]], [[physics]], [[oceanography]], [[hydrology]], [[theoretical planetology]], [[glaciology]], and exoplanetology. Related fields encompass [[space physics]], which delves into the impact of the Sun on the bodies in the Solar System, and [[astrobiology]].

Planetary science comprises interconnected observational and theoretical branches. Observational research entails a combination of [[space exploration]], primarily through robotic spacecraft missions utilizing [[remote sensing]], and comparative experimental work conducted in Earth-based laboratories. The theoretical aspect involves extensive [[mathematical model]]ling and [[computer simulation]].

Typically, planetary scientists are situated within astronomy and physics or Earth sciences departments in universities or research centers. However, there are also dedicated planetary science institutes worldwide. Generally, individuals pursuing a career in planetary science undergo graduate-level studies in one of the Earth sciences, astronomy, astrophysics, geophysics, or physics. They then focus their research within the discipline of planetary science. Major conferences are held annually, and numerous [[academic journal|peer reviewed journals]] cater to the diverse research interests in planetary science. Some planetary scientists are employed by private research centers and frequently engage in collaborative research initiatives.
