The term that takes into consideration the brightness of a star but ignores differences that distance can make is absolute magnitude.

Here's why:

* Absolute magnitude is a measure of a star's intrinsic brightness. It represents how bright a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth. This eliminates the effect of distance on perceived brightness.

* Apparent magnitude is a measure of how bright a star appears from Earth. It is affected by both the star's intrinsic brightness and its distance from Earth.
