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 a stars brightness as if it were a standard distance?
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.
What is the standard unit for measuring the brightness of light, known as the kwe unit?
The standard unit for measuring the brightness of light is called the candela (cd), not the "kwe" unit.
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 is an apparent brightness?
An apparent brightness is the brightness of a star as measured by an observer.
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 are the standard units for apparent brightness?
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.The apparent brightness is assigned a unit called "magnitude", abbreviated "m".

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.
A star's absolute magnitude is its apparent brightness as seen from?
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.
