Which of thede properties is the best measure of a stars brightness

Question

A size
B apparent magnitude
C age
D absolute magnitude

Answer 1

The best measure of a star's brightness among the options provided is:

B apparent magnitude

Apparent magnitude measures how bright a star appears from Earth, taking into account its distance from us and any interstellar material that might affect its brightness. While absolute magnitude (option D) measures the intrinsic brightness of a star at a standard distance, apparent magnitude reflects how bright we perceive the star in the night sky.

So, the correct answer is B apparent magnitude.
