Its magnitude.
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
You can find the luminosity of a main sequence star by measuring its apparent brightness and distance from Earth. Knowing the distance allows you to calculate the star's absolute brightness. Luminosity is then determined by comparing the absolute brightness of the star to that of the Sun, which has a known luminosity.
Luminosity is also known as brightness or radiance, and refers to the total amount of energy emitted by a star or other celestial object per unit time. It is a measure of the intrinsic brightness of an object.
An apparent brightness is the brightness of a star as measured by an observer.
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
the brightness of a star is called it's magnitude
The brightness of a star to an observer on Earth is called it's Apparent Magnitude. The intrinsic brightness of a star is known as it's Absolute Magnitude.
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.

photographs use to measure the brightness of a star
The brightness as seen from Earth is called the "apparent magnitude".The real brightness (defined as the apparent brightness, as seen from a standard distance) is called the "absolute magnitude".
There is no purpose of a star's brightness. They just exist and shine.
An apparent brightness is the brightness of a star as measured by an observer.
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
