  • Mean density: (3.456 ± 0.035) g/cm3
  • Surface area: (8.66 ± 0.2) x 105 km2
  • Surface temperature: 85 K to 270 K or -188.15°C to -3.15°C
  • Surface gravity: 0.25 m/s2
  • Moons: none
  • Orbital distance: 2.152 21 AU – 2.571 38 AU
  • Orbital period: 3.63 years
  • Average orbital speed: 19.34 km/s
  • Escape velocity: 0.36 km/s
  • First recorded: 29 March 1807 by Heinrich Wilhelm Olbers
  • Location: Main Asteroid Belt
  • 25 August 2012 NASA's Down spacecraft used its framing camera to obtain this North side of the asteroid Vesta

  • NASA's Down spacecraft image of Vesta in full view in this mosaic, data for this mosaic was obtained from July 2011 to September 2012. In the bottom of the image we can see towering mountain which is twice as big as Mount Everest

  • Artist's concept shows internal structure of asteroid Vesta, illustration shows everything bast on data from Down mission. Brown innermost core is composed of iron throught to be about 110 kilometres (68 miles) in radius, green mantle and grey is crust

  • 3D image of Vesta shows its eastern hemisphere, image obtained in July 2011 from a distance of 5 200 kilometres (3 200 miles) by NASA's Down spacecraft framing camera
