Vesta, minor-planet designation 4 Vesta, is one of the largest objects in the asteroid belt, with a mean diameter of 525 kilometres (326 mi). It was discovered by the German astronomer Heinrich Wilhelm Olbers on 29 March 1807 and is named after Vesta, the virgin goddess of home and hearth from Roman mythology.
A diameter is an imaginary line running from one side of a circle or sphere through the center to the other side. In comparison to Earth's moon, which has a diameter of about 2100 miles, even the largest asteroids are still pretty small.The rest of the asteroids range in diameter all the way down to less than 5 miles across. Asteroids with diameters of 30 miles or less no longer have a spherical shape.Most asteroids orbit the Sun between Mars and Jupiter. Although some asteroids have sizes comparable to some moons in our solar system, these are not moons because they only orbit the Sun, and not any planets, as the moons do.n comparison to Earth's moon, which has a diameter of about 2100 miles, even the largest asteroids are still pretty small.
