Compared to giant stars like Betelgeuse, how large is the Sun's diameter?
Answer
The Sun is hundreds of times smaller in diameter
When assessing the Sun against the upper limits of stellar size found in the galaxy, our star is quite modest. Stars classified as giants, such as the well-known red giant Betelgeuse, far surpass the Sun in physical scale, possessing diameters hundreds of times greater than that of our star. Furthermore, astronomers have cataloged stars discovered that are up to 100 times larger in diameter than the Sun. Therefore, while the Sun is large compared to the most common stars, it is dwarfed by the extreme, massive stars that represent the upper end of the stellar population spectrum.
