dc.descriptionWe report visible to near-infrared spectroscopy and spectrophotometry of asteroid (21238) 1995 WV7 that reveal the presence of deep absorption bands indicating a V taxonomic type with an apparently basaltic surface composition. Since this asteroid is on the other side of the 3:1 mean motion resonance from Vesta, and because the required ejection velocity from Vesta is in excess of 1.6 km s-1, we conclude that 21238 represents a sample of a differentiated body dynamically unrelated to Vesta.
