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.
Bigger
It ia 250 times as big as the sun
a red giant compared to our sun is about 10-100 times bigger.
The sun is a star. It is comparatively large, believed to be in the top 20% for size.
Saturn - It is larger than both the earth and the moon
Supernova stars' are at least three times the solar mass of the Sun.

Mars is 6,786 Km. in diameter. Big is a relative term. It is big compared to its moons but small compared to the sun
The sun is a star. It is comparatively large, believed to be in the top 20% for size.
Saturn - It is larger than both the earth and the moon
the sun would be pretty small! ( ex. the sun is a soft ball the star Is a soccer ball!)
Probably Eta Carinae, with a radius 400 times the size of our sun.
Supernova stars' are at least three times the solar mass of the Sun.
Big and small are comparatives. The sun is very large compared to the rest of the bodies in our solar system. It is an average sized star. There are stars much larger than the sun.
Pluto is very small compared to earth as earth is compared to the sun.
Big is a comparative word. You need something else with which to contrast it with. North and South America are large compared to Iceland, say, but small compared to the sun.
