A rare class of asteroid distinguished by a moderately high albedo and a reflectance spectrum displaying a strong absorption feature at wavelengths shorter than 0.7 μm. There is also a strong absorption feature at wavelengths near 0.95 μm, in the near-infrared. This dip is characteristic of the silicate mineral pyroxene. The ‘V’ is for Vesta, the first asteroid to be assigned to the class.
