The light from a flashlight can be used to model the apparent magnitude of two stars with the same absolute magnitude by demonstrating how distance affects brightness. Just as a flashlight's light diminishes with distance, the apparent brightness of a star decreases as it moves farther away from an observer. If two stars have the same absolute magnitude but are at different distances, the one closer will appear brighter (higher apparent magnitude) than the one farther away. This relationship illustrates how apparent magnitude depends not only on intrinsic brightness but also on distance from the observer.
The apparent magnitude of Vega is 0.03. The absolute magnitude is 0.58.
Arcturus has an absolute magnitude of -0.29 and an apparent magnitude of -0.04
How far away the star is.
It is actually absolute magnitude, opposed to apparent magnitude which is how much light stars appear to give off.
The apparent magnitude is what we see, and this can be measured directly. The absolute magnitude must be calculated, mainly on the basis of (1) the apparent magnitude, and (2) the star's distance. So, to calculate the absolute magnitude, you must first know the star's distance.
yall dont know that yall losers
Antares Absolute and Apparent Magnitude Absolute Magnitude~ -5.2 Apparent Magnitude~ +0.60
Absolute magnitude is how bright a star is. Apparent magnitude is how bright it looks to us (on Earth).
Apparent magnitude: How bright something looks to us. Absolute magnitude: How bright something really is - expressed as the apparent magnitude it would have at a standard distance.
Apparent magnitude is 0.77 Absolute magnitude is 2.21Wikipedia lists its visual magnitude as 0.77.
Sirius B is a faint white dwarf companion of Sirius A It has an apparent magnitude of +8.3 and an absolute magnitude of +11.18

The apparent magnitude of Vega is 0.03. The absolute magnitude is 0.58.
Betelgeuse has an apparent magnitude of 0.58 and on absolute magnitude of -6.05.
An estimation of the absolute magnitude is −20.9. See related question.
Apparent magnitude is the brightness as observed from earth, while absolute magnitude is the brightness of a star at a set distance. The apparent magnitude considers the stars actual brightness as well as it's distance from us, but absolute magnitude takes the distance factor out so that star brightnesses can be directly compared.
The standard distance is 10 parsecs. At this distance the star's apparent magnitude equals its absolute magnitude. A star 100 parsecs away has an absolute magnitude 5 magnitudes brighter than its apparent magnitude. 1 parsec is 3.26 light-years.
