Absolute magnitude and apparent magnitude. Absolute magnitude is how bright the star actually is. Apparent magnitude is how bright the star appears from a given vantage point. It depends on the star's absolute magnitude and how far away it is.
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.
That's called the star's "absolute magnitude".
An apparent brightness is the brightness of a star as measured by an observer.
A star who's brightness changes is called a variable star.Examples are:AlgolPolarisBetelgeuse.See related link for more information.
Its 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 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 brightness of a star is called it's magnitude
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".
A nova is a star that suddenly increases in brightness.
Absolute Brightness .
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.
