Vesta is a unique, intermediate class of rocky body in the Solar System, between terrestrial planets and small asteroids, because of its size (average radius of ∼263 km) and differentiation, with a crust, mantle and core. Vesta’s low surface gravity (0.25 m/s[superscript 2]) has led to the continual absence of a protective atmosphere and consequently impact cratering and impact-related processes are prevalent.
