Planetary science (or more rarely, planetology) is the scientific study of celestial bodies (such as planets (including Earth), moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and the processes of their formation. It studies objects ranging in sizes from micrometeoroids to huge gas giants, with the aim of determining their composition, dynamics, formation, interrelations and history.
