For a negligible extinction, one can compute the absolute magnitude of an object given its apparent magnitude and luminosity distance : where is the star's actual distance in parsecs (1 parsec is 206,265 astronomical units, approximately 3.2616 light-years).he absolute magnitude is similar to visual magnitude (correctly called apparent magnitude) where a difference of 5 in absolute magnitude corresponds to a factor of 100 in brightness, whereas for apparent magnitude a difference of one in magnitude corresponds to a factor of two in apparent brightness.
