Planetary sciences is an interdisciplinary field that investigates the formation, evolution, and current state of planets, moons, and smaller bodies within and beyond our Solar System using the methods of physics, chemistry, geology, and atmospheric science. It encompasses studies of planetary interiors, surfaces, atmospheres, magnetospheres, and ring systems, as well as orbital dynamics and interactions with stellar radiation and plasma environments. Planetary sciences integrates remote sensing, in situ spacecraft measurements, laboratory experiments, and numerical modeling to constrain processes such as accretion, differentiation, tectonism, volcanism, impact cratering, climate evolution, and potential habitability on diverse planetary bodies.
