Planetary sciences is a multidisciplinary field that focuses on the study of the planets, moons, and other celestial bodies within our solar system and beyond. Researchers in this field study a wide range of topics, including the formation and evolution of planets, planetary atmospheres, geology, surface features, and potential for life on other planets. They use a variety of tools and techniques, such as telescopes, spacecraft missions, and computer modeling, to learn more about the planets and their environments. Planetary sciences seek to enhance our understanding of the origins and dynamics of our solar system, as well as the potential for habitable environments on other planets.
