its called the magnitude dumb *ss
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
the brightness of a star
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.
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.
A nova is a star that suddenly increases in brightness.
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
That type of star is called a supernova. Supernovae occur when a star reaches the end of its life cycle and undergoes a catastrophic explosion, releasing a tremendous amount of energy and increasing its brightness significantly for a brief period of time.
The magnitude is the brightness of the star.
