Two factors that affect a star's apparent brightness are:
1.) The distance between the Earth and the star
2.) The absolute magnitude (the actual brightness) of the star
Hope that helps :P

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 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 apparent magnitude?
a stars brightness as seen from Earth
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.
How does apparent magnitude of a star differ from absolute magnitude?
Apparent magnitude is the brightness as observed from earth, while absolute magnitude is the brightness of a star at a set distance. The apparent magnitude considers the stars actual brightness as well as it's distance from us, but absolute magnitude takes the distance factor out so that star brightnesses can be directly compared.
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 are two ways to describe a stars brightness?
Apparent magnitude and absolute magnitude.
What is a stars level of brightness as viewed by the unaided eye called?
Apparent magnitude.
What stars level of brightness as viewed by the unaided eye is called?
Apparent magnitude.
A stars level of brightness as viewed by the unaided eye is called it's what?
Apparent magnitude.
What is an astrometer?
An astrometer is a device designed to measure the brightness, relation, or apparent magnitude of stars.
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.
