Thus Sol is a G2 (*yellow*) V (main sequence dwarf) star, not ''"A "V" star in this class is in the fifth level of luminosity&mdasha yellow dwarf star."'' The number after the letter determines the luminosity (and thus temperature) of the star within its colour type - a G0 V star is slightly hotter, brighter, larger and more massive than a G2 V which, in turn, is a lot brighter, hotter, larger and more massive than a G8 V star.
