luminosity or brightness
The luminosity of Deneb is about 196,000 times that of the Sun. It's one of the most luminous stars known.
The distance to a Cepheid variable star can be calculated using the period-luminosity relationship, which relates the pulsation period of the star to its intrinsic brightness. By measuring the period of the star and its apparent brightness from Earth, astronomers can determine its distance using the inverse square law for light.
The sun's luminosity, or brightness, is 1 because it serves as the reference point for measuring all other stars' luminosities. Other stars are compared to the sun's luminosity to determine their respective brightness levels.
The main star in the Polaris system has a luminosity which is 2500 times that of the Sun.
The luminosity depends on what stage of its life cycle the star is in. Also, the apparent luminosity depends on the distance from earth.
