There is a star in the Large Magellanic Cloud called R136a1 which has an absolute magnitude of -12.5. Undoubtedly others will turn up as time goes by.
M33-013406.63 in the Traingulm Galaxy has an absolute magnitude of -12.2 to -12.7 (not quite sure of the exact M)
How far away the star is.
VY Canis Majoris has an absolute magnitude of -9.4.
The absolute magnitude is a measure of the star's luminosity hence the smaller the size the less the absolute magnitude.
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.
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 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.
That's the number called the star's "Absolute Magnitude".That is called the star's "absolute magnitude".
Absolute magnitude is how bright a star is. Apparent magnitude is how bright it looks to us (on Earth).
Distance
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.
How far away the star is.
VY Canis Majoris has an absolute magnitude of -9.4.
That's called the star's absolute magnitude.
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.
No. The sun has an absolute magnitude of 4.83. By comparison, Betelgeuse has an absolute magnitude of -5.85. Lower numbers indicate a brighter star. In this case Betelgeuse is actually several thousand times brighter than the sun. The sun is the brightest star as measure by apparent magnitude, which is how bright a star looks from a given location and depends on both absolute magnitude and distance.
-5.1
No. Absolute magnitude is an intrinsic property of the star, but apparent magnitude also depends on the star's distance from Earth.
