Buried by Crystals
Diogenites are made of molten rock that was trapped beneath Vesta's surface. As a result, they cooled much more slowly than the eucrites, so their crystals had more time to grow.
This photo of a diogenite is magnified 40 times—exactly the same amount as the eucrite. The eucrite's smaller crystals indicate that it hardened closer to Vesta's surface.
