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?
Subsequently, question is, how do you measure the brightness of a star? We measure the brightness of these stars using the magnitude scale. The magnitude scale seems a little backwards. The lower the number, the brighter the object is; and the higher the number, the dimmer it is. This scale is logarithmic and set so that every 5 steps up equals a 100 times decrease in brightness.
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.
What color is the brightest star?
The brightest star in our night sky is Sirius, in Canis Major. It has spectral class A and is bluish-white.
