THat is called the star's absolute magnitude. The standard distance is 10 parsecs.

∙ 13y agoA star's brightness is called its magnitude.
The brightness of a star as seen from the Earth is known as its apparent magnitude, and is a function of both its luminosity (brightness) and distance from us.
The actual brightness of a star is called its absolute magnitude; the total amount of electromagnetic radiation it puts out is called its luminosity. The two terms are closely related, and are often used interchangeably.
The definition of a star's absolute magnitude is how bright it would appear to be if it was exactly 10 parsecs away; 10 parsecs equals 32.6 light years.
For example, the red supergiant Antares is 400 light years away. In our sky, its apparent magnitude is around +1.0, or about 2.5 times dimmer than Vega, whose apparent magnitude is 0.0.
But Vega is only 25 light years away, or 16 times closer than Antares is; if you were to travel by spaceship so that you were just 32 light years away from Antares, it would appear to be about a magnitude -4.5 (about the maximum brightness of Venus), which would be well over 100 times brighter than Vega!

If Deneb and Rigel were located at Alpha Centauri's distance from earth how would they appear?
They would both be bright enough to be seen by, and probably too bright to look at
How bright a star appears as seen earth is called?
Apparent magnitude is the brightness of an object as seen from Earth without any atmosphere.
When the earth is at the maximum distance from the sun it is called?
Aphelion.
How do you know the distance between the earth and the sun is not a factor in why there are seasons?
In the northern hemisphere, the Earth is actually closer to the sun during winter than it is in the summer. Seasons are actually caused by the Earth's tilt.
What does it mean when mars is unusually bright?
It probably means it is near to its closest approach to Earth. The distance between Earth and Mars varies a lot as they go around the Sun in their separate orbits.

How bright a star actually is a distance of 32.6 light years from earth is called?
That's called the star's absolute magnitude.
How bright a star actually is at a distance of 32.6 light years away from earth is?
That's the number called the star's "Absolute Magnitude".That is called the star's "absolute magnitude".
What 3 factors affect how bright a star appears from earth?
The 3 factors that affect a star's brightness as viewed from earth, are: The star's age, distance from earth, and actual magnitude (scale a star's brightness is measured in).
How bright does a star appear from earth?
It depends on its intrinsic brilliance and its distance from the observer
What two factors determine how bright a star looks like from earth?
It's luminosity and it's distance from Earth
