Scientific paper

We have evaluated the size of a metallic core and the consequences of magma ocean crystallization in asteroid 4 Vesta, assuming that it is the howardite-eucrite-diogenite (HED) parent body. We assume for Vesta a density of 3.4 g/cc (+/-45% relative error) and a surface gravity of 2.53 x 10-4 M/S squared, based upon a mass of 2.78 x 1023 g and diameter of 540 km.
