Color and Temperature of Star
Spectral class: The color of the star. Hot stars are bluer, cool stars are redder. In descending order from
hottest (most blue) to coolest (most red), the spectral classes are: O B A F G K M. Each spectral class letter can
be subdivided into ten smaller steps or gradations, i.e. class A breaks down into A0 through A9. A0 would be
the hottest class A star (only slightly cooler than B9), while A5 would be half way in between A0 and F0. The
spectral class corresponds to the surface temperature and color as follows:
