A planetary scientist studies planets, moons, and other celestial bodies in our solar system and beyond. They analyze the composition, atmosphere, and geology of these objects to understand their formation and evolution. This field combines aspects of geology, astronomy, and physics to explore the processes that shape planetary bodies. Planetary scientists often use data collected from space missions, telescopes, and laboratory experiments. They may work on projects related to Mars, Jupiter's moons, or even exoplanets. Their research helps us learn more about the universe and the potential for life on other planets.
