How bright can a star get?
Beside this, what does not affect the brightness of a star?
In conclusion, many factors affect the brightness of a star, and these include (but are not limited to) surface area, mass, evolutionary stage, temperature, and distance (if you are talking about apparent magnitude). How are we able to tell if a star is dim start is farther away, or just emitting less light?
Secondly, what two factors determine how bright a star looks from Earth?
The total energy emitted per second by a star is called its luminosity. How bright a star looks from the perspective of Earth is its apparent brightness. The apparent brightness of a star depends on both its luminosity and its distance from Earth.
The brightest star in our night sky is Sirius, in Canis Major. It has spectral class A and is bluish-white.
