“…Another argument against Ceres' density being due to porosity rather than light materials (water) is Ceres' relativity large size. Johnson and Estrada (2009) showed by comparing the density and size of the smaller Solar System objects that the density of objects tended to increase as their size increased and that objects of Ceres' size and larger are not likely to show effects of porosity in determining their bulk density. Also, indirect evidence for the presence of free water ice in large C-class asteroids comes from the recent detection of water ice at the surface of 24 Themis (Rivkin and Emery 2010;Campins et al 2010).…”

Ceres: Its Origin, Evolution and Structure and Dawn’s Potential Contribution

Ceres appears likely to be differentiated and to have experienced planetary evolution processes. This conclusion is based on current geophysical observations and thermodynamic modeling of Ceres' evolution. This makes Ceres similar to a small planet, and in fact it is thought to represent a class of objects from which the inner planets formed. Verification of Ceres' state and understanding of the many steps in achieving it remains a major goal. The Dawn spacecraft and its instrument package are on a mission to observe Ceres from orbit. Observations and potential results are suggested here, based on number of science questions.
