Description: This artist's concept shows the internal structure of the giant asteroid Vesta, based on data from NASA's Dawn mission. Dawn shows that Vesta has an iron core that is about 68 miles (110 kilometers) in radius, suggesting that Vesta completely melted in its early history, allowing iron to sink to form the core and producing a basaltic crust. This illustration shows the innermost core in brown, the mantle in green and the crust in gray.
