Its red-orange hue is unmistakable. Answer (1 of 2): As you probably know, absolute magnitude represents the intrinsic luminosity of a star (how bright it would appear at a standard distance of 10 parsecs). Apparent magnitude. This cannot be seen through the naked eye though. In astronomy, the magnitude of a star refers to its measure of brightness, and while absolute magnitude relates to the star's intrinsic brightness, apparent magnitude, on the other hand, is a way of measuring how bright the object appears in the night sky to us human stargazers back on Earth. It has an apparent magnitude of 13.6 and an absolute magnitude of 11.98.
