What does the brightness of a star mean?
Accordingly, what are the factors that determine 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).
Likewise, what brightness of stars are most common? The Brightest Stars, as Seen from the Earth
|Common Name||Scientific Name||Apparent Magnitude|
|Rigil Kentaurus||Alpha Cen||-0.27|
Additionally, how does distance affect the brightness of a star?
Brightness-Luminosity Relationship: At a particular Luminosity, the more distant an object is, the fainter its apparent brightness becomes as the square of the distance.
What are the two factors that 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.
