The brightness of a star as seen from earth is referred to as brightness.

This statement is correct

Explanation:

There are two ways in which brightness of a star is defined:

Apparent magnitude

It is the brightness of a star measured from an observers perspective i.e., from Earth. The factors that influence apparent magnitude are luminosity, its distance, and any obstruction of the light of the object by interstellar dust along the line of sight to the observer. Apparent magnitude is also known as brightness.

Absolute magnitude

It is the brightness of a star that is measured when the observer is at a distance of 32.6 light-years, or 10 parsecs.

The statement mentioned here is referring to Apparent magnitude.
