The spectroscopic parallax of a star is the difference between the apparent magnitude, which is the brightness of light from the star reaching Earth, and the absolute magnitude, which is the intrinsic brightness. The spectroscopic parallax S can be used to calculate the distance d, in parsecs, from Earth to the star. The relationship is
