4 Vesta, the second most massive asteroid in the Solar System, was the recent target of NASA’s Dawn mission, which spent many months orbiting and analyzing the body. A geologically young (~1 Ga) giant impact basin, Rheasilvia, which has a diameter nearly equal to that of Vesta, dominates Vesta’s southern hemisphere. In addition to opening a massive crater, the impact that formed the Rheasilvia basin produced a shockwave that was sufficiently strong to modify Vesta’s surface morphology on a nearly global scale.
