The intrinsic brightness of a star is called its absolute magnitude. This is a measure of how bright a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth.
Their distance away from you and their intrinsic luminosity.
Absolute magnitude is based on the distance at which a star would appear if it were located at a standard distance of 10 parsecs (32.6 light-years) from Earth. This standardized distance allows astronomers to compare the true brightness of stars regardless of their actual distance from Earth.
The equation for the magnitude of a star is; M=m-5log(d/10) where:M - Absolute magnitude (The brightness of a star viewed 10 parsecs away)m - Apparent magnitude (The brightness of a star as viewed from Earth)d - Distance from the star (Pc)
A star's brightness at a standard distance is referred to as its apparent magnitude. This standard distance is 10 parsecs (32.6 light-years) from Earth. Apparent magnitude allows astronomers to compare the brightness of stars as seen from Earth, regardless of their actual distance from us.

Distance from Earth, size of star, and temperature of star.
Distance from Earth, size of star, and temperature of star.
The three main elements that determine a star's brightness from Earth are its luminosity (intrinsic brightness), distance from Earth, and any intervening dust or gas that may affect the amount of light that reaches Earth.
Your place on the earth, The brightness of the star, Its distance.
No. Brighter distant stars can have the same apparent magnitude as fainter stars that are closer.(Absolute magnitude does not refer to actual brightness, but rather to what the brightness of a star would likely be at an arbitrary distance of 10 parsecs, rather than its actual distance.)
The brightness of a star is primarily determined by its size, temperature, and distance from Earth. Larger, hotter stars tend to appear brighter, while stars that are closer to us also appear brighter due to their proximity. Other factors such as the star's age and its stage in the stellar lifecycle can also influence its brightness.
An apparent magnitude is a measure of how bright a star appears from Earth. The lower the apparent magnitude, the brighter the star appears in the night sky. Negative values indicate very bright stars, while positive values indicate fainter stars.
The idea is that CERTAIN TYPES of stars, including certain variable stars (such as Cepheids) have a known brightness; so if you observe their apparent brightness, you can calculate their distance.
by temperature, size, brightness, distance and color
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
