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.

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.
The intrinsic brightness of a star is called its absolute magnitude. This is a measure of how bright a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.
the moon can vary its brightness and the pink elephant called aphadophalis
Magnitude. First magnitude descibes many bright stars, and a span of five magnitudes represents a difference of a hundred times in the star's brightness. The dimmest stars seen by a perfect human eye in perfect conditions is 6th magnitude.
magnitude for brightness, lightyear for distance, degrees C or K for temperature or colour, solar masses for mass, ...
A photometer is a device used to measure surface brightness. It detects and quantifies the amount of light emitted by a surface, typically in astronomy to measure the brightness of stars and galaxies.
An astrometer is a device designed to measure the brightness, relation, or apparent magnitude of stars.
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
Scientists actually use two measurements to identify a star's brightness. One is luminosity, or the energy that star puts out. Another is magnitude, or the amount of light a star puts out.
The standard measure used to determine the brightness of a light bulb is called lumens.
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
