2.0. THE SUN The sun is just an average star. Of the innumerable others, some are larger and others smaller, some are whiter and others show colours that are more inclined to red, some are believed to be older and others younger. Its absolute magnitude is 4.48, its spectral type G2, it is a dwarf and its surface temperature is about 6000 K. But it has something special and unique, the sun is 'our' star and the 'only' star whose shape and surface may be observed.
