Planetary sciences is the field of study focused on understanding planets, moons, and other celestial bodies in our solar system and beyond. It combines aspects of geology, astronomy, chemistry, and physics to explore how these objects form, evolve, and interact. By studying planetary atmospheres, surfaces, and interiors, scientists uncover clues about each planet’s history and the potential for life. Planetary science also delves into the study of asteroids, comets, and dwarf planets, which hold secrets about the early solar system. Through missions, telescopes, and simulations, planetary scientists piece together the story of our cosmic neighbourhood and its place in the universe.
