What two factor affect a stars apparent brightness?

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 are two ways to describe a stars brightness?

Apparent magnitude and absolute magnitude.


What two things must an astronomers find out in order to calculate a star's absolute brightness?

It's distance from Earth and the star's actual brightness


Why do some stars appear bigger and brighter than others?

A stars brightness depends on two factors; its distance from us and its actual brightness (absolute magnitude). The actual brightness of a star depends on various factors, such as its mass, its temperature and its age.Consider two stars of the same actual brightness (absolute magnitude) - if one of them is much closer, then is will be brighter than the further one. It will appear brighter, even though it would be the same side by side - it can be said to be apparently brighter (higher apparent magnitude) due to its distance.A:They appear bigger and brighter because they really are bigger and brighter, but even if they are not bigger and brighter it could be because they are closer.

distance from the sun and the age of the star


What are two types of magnitude in space?

The two types of magnitude in space are (from what my textbook says) absolute and apperant brightness. HOPE I HELPED!!!


What two things does a stars absolute magnitude depend?

Mass and age.


A sentence for absolute magnitude?

Two stars may look, for us, like they have about the same brightness, but it may be that one is a hundred times farther away... and 10,000 times brighter. The two things cancel out in this example. The "absolute brightness" tells us how bright a star or other object REALLY is. It is defined as how bright the object looks at a standard distance.
