The star with the greatest absolute magnitude is typically a supergiant star, such as a blue supergiant like Rigel or a red supergiant like Betelgeuse. These stars can have absolute magnitudes of around -6 to -12, depending on their size and luminosity. In contrast, the absolute magnitude of our Sun is about +4.83, illustrating the immense brightness of supergiants compared to other stars. Generally, more massive stars tend to have more negative absolute magnitudes, indicating higher luminosity.
A star near the Sun might be brighter or dimmer, it depends on how big it is. Each star has an absolute magnitude and if you find out a star's absolute magnitude, and then subtract 31.4, that would be its visual magnitude at the Sun's distance from us.
The absolute magnitude of a star is a measure of its true brightness if it were placed at a standard distance of 10 parsecs from Earth. To calculate the absolute magnitude from the apparent magnitude (m) of 6, you would need to know the star's distance. Without this information, we cannot determine the absolute magnitude.
How far away the star is.
The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.The standard distance used for evaluating absolute magnitude is 10 parsec.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
Beta Aquarii (Sadalsuud) has an apparent magnitude of 2.89 and an absolute magnitude of -4.5.
The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.The star is called Altair; the absolute magnitude is estimated at 2.21.
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.
That's the number called the star's "Absolute Magnitude".That is called the star's "absolute magnitude".
Apparent magnitude is the measure of how bright a star appears to be from our vantage point. Absolute magnitude is the measure of how bright a star would be if it were located 10 parsecs from earth.

No; the "magnitude" is how bright the star is. It can either mean:* The apparent magnitude = how bright it seems to us, * The absolute magnitude = how bright the star really is (i.e., how bright it would seem at a standard distance).
Absolute magnitude is how bright a star is. Apparent magnitude is how bright it looks to us (on Earth).
Distance
The absolute magnitude of a star is a measure of its true brightness if it were placed at a standard distance of 10 parsecs from Earth. To calculate the absolute magnitude from the apparent magnitude (m) of 6, you would need to know the star's distance. Without this information, we cannot determine the absolute magnitude.
That means how bright the star really is. The "absolute magnitude" is defined as how bright the star would look if it were at a standard distance from us.
distance from the Earth. The apparent magnitude of a star is how bright it appears from Earth, while the absolute magnitude is how bright a star would be if it were located at a standard distance of 10 parsecs away from Earth. The difference in magnitude is primarily influenced by the star's distance, with closer stars having a smaller difference and more distant stars having a larger difference between their apparent and absolute magnitude.
