The brightness of a star depends on its composition i.e. size and temperature (energy light radiation e.g. X-ray, etc.) and how far it is from the planet.
Explanation:
A star’s apparent brightness is determined by its luminosity as well as its distance from Earth. As a result, calculating a star’s luminosity requires only determining its apparent brightness and measuring its distance from it.
