Betelgeuse (also known as alpha ori) is a very large star, an M supergiant. This is because it has evolved far from the state in which stars spend most of their lives, known as the main sequence. For stars on the main sequence, which includes our Sun, there is simple proportionality between size and mass, and also a simple scaling for luminosity. For evolved stars the situation is less simple. Betelgeuse is more than 1000 times larger than the Sun, and 50000 times as luminous, but only about 20 times as massive. Most of the light from Betelgeuse comes out in the infrared, however, which is very different from the Sun. One consequence of the advanced evolutionary state of Betelgeuse is that it probably was much more massive when it was on the main sequence, and has already lost a significant fraction of its mass (probably more than half) in a stellar wind.

Which is larger the moon or the sun?
The sun is larger than the moon. While the sun has a diameter of about 1.4 million kilometers, the moon's diameter is around 3,474 kilometers.
What is the sun is the sun big or small?
The sun is a medium-sized star compared to others in the universe. It is classified as a G-type main-sequence star, or more commonly known as a yellow dwarf star. Its size appears large to us because it is the closest star to Earth.
How big is Betelgeuse compared from the sun?
Betelgeuse is much larger than the Sun. It is a red supergiant star, with a radius around 650-900 times larger than the Sun. If placed in our solar system, Betelgeuse would engulf all the inner planets including Jupiter.
How big is the sun compared to a star?
The sun is an average-sized star compared to other stars in the universe. It is classified as a G-type main-sequence star and is larger than many other stars but smaller than some of the largest stars known.
Stars that are much larger than the sun are called?
Stars that are much larger than the sun are called supergiants. These massive stars have much greater luminosity and can be tens to hundreds of times larger in size compared to the sun.
