Star brightness is defined in terms of apparent magnitude, which is how bright the star appears from Earth. Star brightness is also defined by absolute magnitude, which is how bright a star appears at the standard distance of 36.2 light years. Luminosity is also a way that a star's light is measured.

A star's brightness as if it were a standard distance is called?
Absolute Brightness .
What term is used to describe a star's brightness?
It is called Vmag. This is the visual magnitude of the object. Visual magnitude is a scale used by astronomers to measure the brightness of a star or other celestial object. Visual magnitude measures only the visible light from the object. The lower the V-MAG the brighter the star. You can go to http://seasky.org/pictures/sky7b14.html to learn more.
What units of measurement do you measure the brightness of stars?
there are two separate ways that astronomers measure the brightness of a start, there is actuall and aparent brightness. In apparent brightness, the measure how bright it looks to all the humans on Earth. However, the actual brightness of a star is different. Say a star is really, really bright, but really far away. That star would look preety dim. Or if a star is not so bright, but really close, like the Sun. The actuall brightness of a star is harder to measure, but is possible by use of waves and stuff like that, I don't know too much about actuall brightness
The measure of a stars brightness is called its what?
Scientists actually use two measurements to identify a star's brightness. One is luminosity, or the energy that star puts out. Another is magnitude, or the amount of light a star puts out.
What is a first magnitude star called?
The term magnitude is used to define the apparent brightness of an object from Earth. The scale has its origins in the Hellenistic practice of dividing stars, visible to the naked eye into six magnitudes.The brightest stars were said to be of first magnitudewhile the faintest were of sixth magnitude by visual perception.Each magnitude was considered to be twice the brightness of the following grade (a logarithmic scale).Nowadays there are more than six magnitudes and the use of negative values were introduced. So our Sun have an apparent magnitude of -26.73 whilst Uranus is 5.5See related for for information
What is the brightness of a star measurable by a scale called?
It is called the magnitude scale. It is a log scale.

What the measure of a stars brightness called?
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.
What is the measure of the star's brightness?

What is a star brightness called?
the brightness of a star is called it's magnitude
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 it called when a star suddenly increases in brightness?
A nova is a star that suddenly increases in brightness.
A star's brightness as if it were a standard distance is called?
Absolute Brightness .
What is it called when brightness is how bright a star seems or looks?
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.
