The apparent magnitude of Betegeuse is 0.5 and it has an M2 spectrum making it a red star. Its distance is 420 light years and its absolute magnitude is -4.5 so it is 9 magnitudes brighter than the Sun; that is 4000 times brighter, so it's a giant. It is slightly variable in its brightness.
At the same distance the Sun would be a 9th magnitude star, invisible except in a telescope.

What is the apparrent magnitude of the star 'Arcturus'?
The apparent magnitude of Arcturus is approximately -0.04, making it one of the brightest stars in the sky. This makes Arcturus visible to the naked eye and a prominent object in the northern hemisphere during certain times of the year.
What part of a star is called magnitude?
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
Which is what star would be the brightest magnitude 1st 2nd 3rd?
A star with a magnitude of 1 is the brightest, followed by a magnitude of 2 and then a magnitude of 3. The lower the magnitude, the brighter the star appears in the sky.
A first magnitude star is times brighter than a 5th magnitude star?
For apparent magnitudes, a magnitude of zero has the same magnitude as Vega. A first magnitude star is 40 percent as bright and a fifth magnitude star is one percent. So, a first magnitude star is 40 times as bright as a fifth.
What is the magnitude for Thuban the star?
the magnitude is 3.6.
What star has greater magnitude then Sirius?
Betelguese
What is the apparrent magnitude of the star 'Arcturus'?

Is betelguese a main sequence star?
It is a supergiant, so no.
What will be the next star to be blow up?
Scientists reckon betelguese is the next star to blow up
What is a star brightness called?
the brightness of a star is called it's magnitude
Star A is a first magnitude star. Star B is a sixth magnitude star. Which star is brighter and by how much?

What is star's magnitude?
The magnitude is the brightness of the star.
What part of a star is called magnitude?
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
What is the magnitude of a star as it appears in the sky called?
The Polar star is the star that is magnitude. This is a Luminosity star.
What star is called its magnitude?
The magnitude of a star means how bright it is.
What is the distance between an eighth magnitude star and a 9th magnitude star?
The 8th magnitude star is about 2.5 times brighter.
Is a third-magnitude star ten times as bright as a fourth-magnitude star?
No. The difference in 1 magnitude is the 5th root of 100 which is about 2.512. So a 3rd magnitude star is 2.512 times as bright as a 4th magnitude star.
