Asteroid evolution is the study of how asteroids have changed over time, both physically and chemically. This research area aims to understand the processes that affect asteroids, such as collisions, heating, and cooling, and how these processes have shaped the current population of asteroids in our solar system. By studying asteroid evolution, scientists can gain insight into the formation and early history of our solar system, as well as potential hazards posed by near-Earth asteroids. This research area often involves the use of observational data from telescopes and spacecraft, as well as theoretical modeling and laboratory experiments.
