Approximately 6% of main-belt asteroids are vestoids,[citation needed] with Vesta being by far the largest of them.
A large proportion of vestoids have orbital elements similar to those of Vesta, either close enough to be part of the Vesta family, or having similar eccentricities and inclinations but with a semi-major axis lying between about 2.18 AU and the 3:1 Kirkwood gap at 2.50 AU.
The visible wavelength spectrum of the V-type asteroids (including 4 Vesta itself) is similar to the spectra of basaltic achondrite HED meteorites.
A J-type has been suggested for asteroids having a particularly strong 1 μm absorption band similar to diogenite meteorites,[3] likely being derived from deeper parts of the crust of 4 Vesta.
Impacts of V-NEAs on the Earth, according to the known sample (data taken in 2016), occur once in about 12 million years and have the potential to cause disastrous effects on regional to global scale, producing craters as large as 30 km in diameter and releasing kinetic energy of as much as 3 Mt.
