Stars are classified by their spectra (the elements that they absorb) and their temperature. In general, an ordinary (hydrogen-fusing, or main-sequence) star of spectral type A is hotter than a star of spectral type K. Spectral types are a way of classifying stars according to their color or what spectral lines we see in their light.رثاء صديق
