The apparent brightness is assigned a unit called "magnitude", abbreviated "m". Lower numbers mean a brighter star. It is a logarithmic scale, such that every 5 numbers represent a factor of 100; a difference of 1m corresponds, approximately, to a factor of 2.5.

A star's brightness is the brightness seen by humans on Earth. A star's brightness is its actual brightness and does not depend on where the star is viewed from.?
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".
What terms takes into consideration the brightness of a star but ignores the differences that distance can make?
"Apparent magnitude" is the star's brightness after the effects of distance. "Absolute magnitude" is the star's brightness at a standard distance.
What is a synonym for absolute magnitude and apparent magnitude?
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.
Define standard candle as it is used in astronomy?
A "standard candle" in astronomy is an object whose luminosity (its true brightness, not just how bright it seems to us) can be estimated, based on characteristics of that type of object. Then its distance can be estimated from its "apparent magnitude". The stars called "Cepheid variables" are a good example. The rate at which their brightness varies is closely linked to their luminosity.
What is different shape between apparent and absolute magnitude of stars?
This has nothing to do with shape. The apparent magnitude means how bright a star looks to us. The absolute magnitude means how bright the star really is (expressed as: how bright would it look at a standard distance).
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is a stars brightness as if it were a standard distance?
Theres `Absolute Magnitude` which is the brightness of a star at a set distance. Then there is `Apparent Magnitude` which is the apparent brightness from earth, regardless of distance.

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".
What is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
What is similarities between apparent brightness and absolute brightness?
Both relate to brightness; both are measured in the same units; both are used for astronomical objects such as stars or galaxies.
What does measurement of the brightness of a star call?
Brightness of stars (apparent and absolute magnitude) is measured by convention, taking an another star as a standard.
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is difference between apparent brightness and absolute brightness?
Absolute Brightness: How bright a star appears at a certain distance. Apparent Brightness: The brightness of a star as seen from Earth.
What is the apparent brightness of the stars?
Astronomers define star brightness in terms of apparent magnitude how bright the star appears from Earth and absolute magnitude how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs.
What terms takes into consideration the brightness of a star but ignores the differences that distance can make?
"Apparent magnitude" is the star's brightness after the effects of distance. "Absolute magnitude" is the star's brightness at a standard distance.
What is difference between apparent brightness and true brightness?
Apparent brightness: how bright an object - such as a star - looks to us. True brightness: how bright such an object really is. Defined as: how bright it would look at a standard distance.
What is a synonym for absolute magnitude and apparent magnitude?
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.
