Question

which of the following statements accurately describes apparent and absolute magnitude?
apparent magnitude measures how bright a star appears from earth, and absolute magnitude measures the actual brightness regardless of the stars distance from earth.
absolute magnitude measures how bright a star appears from earth, and apparent magnitude measures the actual brightness regardless of the stars distance from earth.
absolute magnitude measures the stars distance from earth, and apparent magnitude measures the stars surface temperature.
apparent magnitude measures a stars surface temperature, and absolute magnitude measures the stars internal temperature.

Explanation:

Apparent magnitude is about a star's brightness as seen from Earth. Absolute magnitude is the actual brightness (luminosity) of a star, calculated as if the star were at a standard distance (10 parsecs) from Earth, so it's independent of the star's actual distance from Earth.

Answer:

Apparent magnitude measures how bright a star appears from Earth, and absolute magnitude measures the actual brightness regardless of the star's distance from Earth.
