The Dawn mission will determine the topography, gravity, and rotational state of Vesta, allowing the indirect study of its interior structure. We explore the extent to which we will be able to determine the characteristics of the interior features, using a Monte Carlo approach. The shape and density of core, mantle, and crust are parametrized and independently sampled, in order to generate a gravity solution that can be compared directly with the data. This method is particularly suited to explore the full extent of physical solutions that are compatible with the data. Several scenarios for the interior structure of Vesta (strongly differentiated, weakly differentiated, almost uniform density) will be assumed and tested, in order to assess to which level of detail each one can be reconstructed.
