The best way to describe the brightness of a star is by using its absolute magnitude. Absolute magnitude is a measure of how bright a star would appear if it were located at a standard distance of 10 parsecs (about 32.6 light-years) from Earth, allowing for a consistent comparison of intrinsic brightness among stars.
