Stars are classified by their spectral type and absolute magnitude. The main spectral types run OBAFGKM, in order of decreasing temperature. The absolute magnitude is the brightness of the star corrected for distance. A plot of these two characteristics for a group of stars is called a Hertzsprung-Russel diagram.
