Diogenite Meteorites - From 4 Vesta Asteroid

Diogenits meteorites are a class of achondritic (stony) meteorites believed to originate from the inner crust of the asteroid or minor planet 4 Vesta. How many people know there is a minor planet called 4 Vesta in our solar system, let alone we have found meteorites on Earth which were once part of it? It is one of just seven bodies in the Solar System that humans have physical samples of.
