WHAT DOES DISTANCE MODULUS MEAN IN ENGLISH?
Definition of distance modulus in the English dictionary
The definition of distance modulus in the dictionary is a measure of the distance, r, of a celestial object too far away to show measurable parallax. It is given by m– M = 5 log, where m is its apparent magnitude and M is its absolute magnitude.
