Our sun has an absolute magnitude of 4.83, compared to Betelgeuse's absolute magnitude of -6.05. This means that Betelgeuse is more than 10 magnitudes brighter than our sun.

Is Betelgeuse warmer than the sun?
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
Is Vega or Betelgeuse the brightest star?
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.
What is the suns absolute magnitude from earth?
You cannot ask for an absolute magnitude and specify the distance, as the absolute magnitude is derived from a set distance of 32.616 light years.At that distance, the absolute magnitude of the Sun is +4.83From Earth the apparent magnitude -26.74
What is the absolute magnitude of most blue stars?
They would have different sizes, but all much larger than our Sun, being hundreds of times larger. If some of them were where our Sun is now, we would be inside the star because they would reach out beyond where we are in relation to our Sun.
What kind of star is Betelgeuse exactly?
The star called Betelgeuse is a red giant. It is about 700 times the size of the sun, and its temperature is lower than that of the sun's, at around 6,000 degrees Fahrenheit.
Does the absolute magnitude of the sun show that it is the brightest star?
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.
How bright is a star really is?
We use the phrase "absolute magnitude" to describe how bright a star really is, and "apparent magnitude" to describe how bright it looks from Earth. The lower the number, the brighter the star. Like the Richter scale of earthquakes, the scale is logarithmic; a change of "1" indicates a difference of a factor of 10. For example, the bright red supergiant star Betelgeuse, at the upper left corner of the constellation Orion, has an absolute magnitude of -5.14, and an apparent magnitude of 0.58. Our Sun has an absolute magnitude of 4.83, and an apparent magnitude of -27.6.
Is Betelgeuse warmer than the sun?
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
Does the star Vega produce more light than the Betelgeuse star?
No. Check the absolute magnitudes, for example in Wikipedia or in Wolfram Alpha. The LOWER numbers refer to a HIGHER brightness (for visible magnitude) or total power output (for bolometric magnitude).
Is Vega or Betelgeuse the brightest star?
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.

How will a star bright if it was near the sun?
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.
What is the absolute magnitude of most blue stars?
They would have different sizes, but all much larger than our Sun, being hundreds of times larger. If some of them were where our Sun is now, we would be inside the star because they would reach out beyond where we are in relation to our Sun.
The true brightness of a star is called its BLANK magnitude?
The scale of star brightness is the 'magnitude'. The definition of the magnitude is: A change of six magnitudes equals a factor of 100. So one magnitude change is a factor equal to the 6th root of 100 = about 2.15443 (rounded)
What is the sun's magnitude and distance from Earth?
The Sun has an absolute magnitude of about 4.8 and an apparent (visual) magnitude of around -26.7. It's roughly 150,000,000 km from Earth on average.
What kind of star is Betelgeuse exactly?
The star called Betelgeuse is a red giant. It is about 700 times the size of the sun, and its temperature is lower than that of the sun's, at around 6,000 degrees Fahrenheit.
What is the magnitude of the sun?
