How much brighter is Betelgeuse than our Sun?
Betelgeuse is approximately 100,000 times brighter than our Sun. This red supergiant star, located in the Orion constellation, has an absolute magnitude of about -5.14, compared to the Sun's absolute magnitude of about +4.83. Its immense brightness is due to its size and the advanced stage of its stellar evolution.
Is Betelgeuse warmer than the sun?
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
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 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 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 much brighter is Betelgeuse than our Sun?
Betelgeuse is approximately 100,000 times brighter than our Sun. This red supergiant star, located in the Orion constellation, has an absolute magnitude of about -5.14, compared to the Sun's absolute magnitude of about +4.83. Its immense brightness is due to its size and the advanced stage of its stellar evolution.
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.
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 Betelgeuse warmer than the sun?
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
Which star would have the greatest absolute magnitude?
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.
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.
What is the suns absolute magnitude from earth?

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.
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 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.
