WebJan 11, 1997 · Knowing the distance and apparent brightness of a star, we can determine its intrinsic luminosity using the equation f=L/4`pi'd 2. A color of a star is defined by the ratio of its apparent brightness (flux) through two different filters, which cover different ranges of wavelength. Observed stars have an enormous range of apparent brightness.
