An apparent brightness is the brightness of a star as measured by an observer.
A star's brightness at a standard distance is referred to as its apparent magnitude. This standard distance is 10 parsecs (32.6 light-years) from Earth. Apparent magnitude allows astronomers to compare the brightness of stars as seen from Earth, regardless of their actual distance from us.
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
A star's absolute magnitude is its brightness as seen from a standard distance of 32.6 light-years away. It accounts for the intrinsic brightness of the star without regard to its distance from Earth.
Apparent magnitude.
apparent magnitude (brightness of a star when viewed from Earth) depends on the size of the star, how hot it is, and its distance from Earth
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.

A star's brightness at a standard distance is referred to as its apparent magnitude. This standard distance is 10 parsecs (32.6 light-years) from Earth. Apparent magnitude allows astronomers to compare the brightness of stars as seen from Earth, regardless of their actual distance from us.
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".
Magnitude
the apparent magnitude of the star mizar is -7.48 !
The apparent brightness of a star is represented by its apparent magnitude, which is a logarithmic scale used to measure the brightness of celestial objects as seen from Earth. The lower the apparent magnitude number, the brighter the star appears in the sky. Each increase of one magnitude corresponds to a brightness factor of 2.5.
The apparent magnitude of a star is a measure of its brightness.
Apparent magnitude.
brightness
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
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.
