Miss the sunrise this morning? No worries. @NASAJPL (the Jet Propulsion Labs at NASA) gives you a virtual fly-over of the asteroid Vesta, composited from the many topographical photos taken by the Dawn mission. The video below shows the craters, mountains and other features of this 330 mile wide satellite that orbits our sun in the asteroid belt.
And Vesta is big: it comprises an estimated 9% of the total mass of the asteroid belt – which is the ring of asteroids and debris that orbits between Mars and Jupiter. It is considered the most geologically-diverse of the asteroids studied so far, containing huge features including a crater 285 miles across – nearly the whole diameter! – that is evidence of an impact with another object.
In fact, Vesta just behind to the dwarf planet Ceres in size, making it nearly big enough to sit in the same pantheon of semi-planets as the former planet Pluto.http://www.jpl.nasa.gov/videos/asteroids/20120510/vestaflyover20120510-1280.m4v?
