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?

One way to describe a star's brightness is by its apparent magnitude, which is how bright it appears from Earth. Another way is by its absolute magnitude, which measures how bright a star would appear if it were placed at a standard distance of 10 parsecs from Earth.


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.

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 are two factors that determine the brightness of a star?

Two factors that determine the brightness of a star are its size (larger stars are generally brighter) and its distance from Earth (closer stars appear brighter).


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.


Will there be a difference between the two circuits in bulb brightness why or why not?

Yes, there may be a difference in bulb brightness depending on factors like the voltage applied, resistance in the circuit, and the type of bulb used. These factors can affect the current flowing through the bulb, ultimately impacting its brightness.
