Apparent magnitude
Explanation:
Brightness of a star depends upon the distance, size and temperature of the star. The brightness is represented by magnitude. These are the numbers which extend towards both negative and positive axis. more negative means more bright. Apparent magnitude represents the brightness of the star as observed from the Earth. Absolute magnitude represents the brightness of the star at a distance of 10 parsec from Earth.
