The brightness of a star depends on its temperature, size and distance from the earth. The measure of a star's brightness is called its magnitude. Bright stars are first magnitude stars. Second magnitude stars are dimmer. The larger the magnitude number, the dimmer is the star.
The magnitude of stars may be apparent or absolute.
The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.
This has nothing to do with shape. The apparent magnitude means how bright a star looks to us. The absolute magnitude means how bright the star really is (expressed as: how bright would it look at a standard distance).
"Apparent magnitude" is the star's brightness after the effects of distance. "Absolute magnitude" is the star's brightness at a standard distance.
Astronomers define star brightness in terms of apparent magnitude (how bright the star appears from Earth) and absolute magnitude (how bright the star appears at a standard distance of 32.6 light years, or 10 parsecs).
Our Sun is pretty much average. It's larger than about 60 to 70 % of the other stars in the Milky Way; the estimate increases as we keep discovering more and more very small and very dim brown dwarf "stars" (that are right on the boundary between "star" and "not star").
Magnitude is a measure of brightness, there is no relationship with density.
The 8th magnitude star is about 2.5 times brighter.
The brightness of a star is not affected by its magnitude/size but is instead affected by the heat at which the star burns.
The relationship between luminosity and magnitude in stars is that luminosity measures the total amount of light a star emits, while magnitude measures how bright a star appears from Earth. A star's luminosity is its actual brightness, while its magnitude is its apparent brightness as seen from Earth. The lower the magnitude, the brighter the star appears, and the higher the luminosity, the more light the star emits.
The magnitude of a star is a measure of its brightness as seen from Earth, while luminosity is the total amount of energy a star emits. The relationship between magnitude and luminosity of a star is that a star's luminosity is directly related to its magnitude - the brighter a star appears (lower magnitude), the higher its luminosity.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
yes yes it does
apparent magnitude (brightness of a star when viewed from Earth) depends on the size of the star, how hot it is, and its distance from Earth
The Hertzsprung-Russell (HR) diagram is a graph that shows the relationship between a star's magnitude (luminosity) and temperature. It plots stars based on their color (temperature) and brightness (magnitude), allowing astronomers to classify stars and understand their evolutionary stage.
The two types are apparent magnitude, the magnitude of a star as it appears to us, and absolute magnitude, which is what a star's apparent magnitude would be at a standard distance of ten parsecs.
The apparent magnitude of a star is dependent on the star's size, temperature and distance from where it is observed. An absolute magnitude is determined by the same three factors, but the distance is fixed at 10 parsecs.
The answer to this question is Hertzsprung-Russell diagram
