V-type asteroid
The V-type asteroids or Vestoids are moderately bright, and very similar to the more common S-type, which are also made up of stony irons and ordinary chondrites. The only significant difference between this rarer form of asteroid is that it contains more pyroxene than the more commonly found S-type. The spectrum has a strong absorption feature shortwards of 0.7 µm, and near 1 µm.
It is thought that most or all V-type asteroids originated as fragments from the crust of the asteroid 4 Vesta, possibly blasted out by a single very large impact at some point in Vesta's history.
