The term used to describe the actual amount of light given off by a star at standard distance is absolute magnitude.

Here's why:

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

* This standardized distance allows astronomers to compare the true luminosity of stars regardless of their actual distance from us.

In contrast, apparent magnitude is the brightness of a star as observed from Earth. It is affected by both the star's intrinsic brightness and its distance from Earth.
