Asteroid geology is the study of the physical and chemical properties of asteroids, small rocky bodies that orbit the Sun. Asteroids are remnants from the early formation of the solar system and can provide valuable insight into the processes that occurred during this time. Researchers in this field study the composition, structure, formation, and evolution of asteroids in order to better understand their role in the solar system and their potential impact on Earth. Techniques used in asteroid geology include remote sensing, spectroscopy, and laboratory analysis of meteorite samples. This research area is important for advancing our knowledge of the solar system's history and for assessing the potential risks posed by asteroids to Earth.
