Planetary Geology is the study of the geology of celestial bodies, including planets, moons, asteroids, and comets. It involves understanding the composition, structure, and processes that shape these bodies, much like how Earth’s geology is studied. By examining features such as craters, mountains, and valleys, scientists can learn about the history and evolution of these celestial objects. This field combines aspects of geology, astronomy, and planetary science to explore how different forces, such as volcanism and erosion, have influenced the surfaces of planets like Mars and Venus. Through missions and observations, researchers gather data that helps us understand not only our solar system but also the potential for life beyond Earth.
