A window into the interior of asteroid Vesta

Authors


Abstract

On the asteroid Vesta, a large, deep impact basin, called Rheasilvia, exposes the mantle below the asteroid's crust, providing a window into Vesta's interior. The impact that formed the basin is thought to have kicked out pieces of Vesta to form the Vestoids, smaller asteroids whose orbits suggest that they originated from Vesta. The Vestoids may be the parent bodies of the howardite-eucrite-diogenite (HED) meteorites.
