Is Vesta a Protoplanet? (Probably Not!)

Vesta has long been known to be the source of the HED meteorites, and the recent Dawn mission was sent there to inspect, close up, an intact protoplanet from the origin of the solar system. Except... Vesta's overall density is too low, and its core and crust too big, to fit anything like what we expect an intact protoplanet to look like. Instead, we will explore more exotic theories of Vestan formation and evolution in a violent early solar nebula.
