A 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!

Yes, we can see stars that are much farther away than that. If the sun were 32.6 light years away, it would be just an average star in the night sky.
The apparent magnitude a star would have if it were at a distance of ten parsecs (which is about 32.6 light years) from Earth is its absolute magnitude.
Its absolute magnitude (or absolute brightness). The standard distance used is 10 parsecs, about 32.6 light-years.
Denebola, 15 L☉
Naos
They would both be bright enough to be seen by, and probably too bright to look at
Apparent magnitude is the brightness of an object as seen from Earth without any atmosphere.
Aphelion.
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.
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.
the absolute answer is absolute magnitude to be

That's called the star's absolute magnitude.
That's the number called the star's "Absolute Magnitude".That is called the star's "absolute magnitude".
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).
It depends on its intrinsic brilliance and its distance from the observer
It's luminosity and it's distance from Earth
This is called "Apparent Magnitude".
How bright the object would be if it was the same distance from Earth as the sun is
