Updated: 6/23/2024

The apparent magnitude of the Sun is -26.73. (Yes negative)

The absolute magnitude of the Sun is 4.83

See related question for the difference between absolute and apparent magnitude.

For comparison at maximum brightness.

Full Moon -12.6
Venus -3.8
Mars - 3
Sirius -1.47
Ganymede 4.6
Object visible with the naked eye 6.5

Does our sun have a lower absolute magnitude then Betelgeuse?

No, Betelgeuse has a lower absolute magnitude compared to the Sun. Betelgeuse is a red supergiant star with a much larger luminosity, making it appear brighter despite its greater distance from Earth.

Is sun the brightest star?

The brightness of a star is usually referred to as its magnitude. Every star has two magnitudes. The apparent magnitude is how bright it appears to us here on earth. The absolute magnitude is the apparent magnitude that the star would have, if it were viewed from a standard distance. The apparent magnitude of our sun is vastly greater than that of any other celestial object. In terms of absolute magnitude, our sun can't begin to compare with some of the big bright stars in the universe.

Is Mizar brighter than the Sun?

Yes, in "absolute magnitude", Mizar is much brighter than the Sun.

Explain a stars apparent magnitude and absolute magnitude?

Apparent magnitude is the brightness of an object as seen from Earth without any atmosphere.Absolute magnitude is the brightness of an object as seen from a predetermined distance, depending on the object.For planets, the distance used is 1 AU (Astronomical Units). Stars and galaxies use 10 parsecs which is about 32.616 light years.The dimmer an object is the higher the positive value. The brighter an object is the higher the negative value.Examples:The Sun has an apparent magnitude of -26.74 but an absolute magnitude of 4.83Sirius has an apparent magnitude of -1.46 but an absolute magnitude of -1.42This means that from Earth, the Sun is a lot brighter, but if the Sun was replaced by Sirius, Sirius would be 25 times more luminous.See related links for more information

Which magnitude of star is brighter -5 or 2?

A magnitude of -5 is brighter than a magnitude of 2. The magnitude scale used in astronomy is inverted, meaning the lower the number, the brighter the object. So, a negative magnitude indicates a brighter star than a positive magnitude.

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 is the sun's magnitude?

-26.7 -26.7

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 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.

Does our sun have a lower absolute magnitude then Betelgeuse?

No, Betelgeuse has a lower absolute magnitude compared to the Sun. Betelgeuse is a red supergiant star with a much larger luminosity, making it appear brighter despite its greater distance from Earth.

Would the apparent magnitude of the sun increase or decrease if it were farther away from Earth?

The apparent magnitude of the Sun would decrease if it were farther away from Earth. Apparent magnitude is a measure of an object's brightness as seen from the observer's vantage point, and the brightness of the Sun decreases with distance.

Is sun the brightest star?

The brightness of a star is usually referred to as its magnitude. Every star has two magnitudes. The apparent magnitude is how bright it appears to us here on earth. The absolute magnitude is the apparent magnitude that the star would have, if it were viewed from a standard distance. The apparent magnitude of our sun is vastly greater than that of any other celestial object. In terms of absolute magnitude, our sun can't begin to compare with some of the big bright stars in the universe.

Why does the sun have the lowest magnitude number of all stars?

The sun has the lowest magnitude number of all stars because it is the closest star to Earth and appears brighter to us. Magnitude numbers are a measure of brightness, with lower numbers indicating brighter objects. Therefore, even though the sun is an average star in terms of luminosity, its proximity makes it the brightest object in our sky and gives it the lowest magnitude number.

Is Mizar brighter than the Sun?

Yes, in "absolute magnitude", Mizar is much brighter than the Sun.

What is a sentence for Absulute Magnitude?
