The Sun: Not An Average Yellow Star
... Most stars in the Universe are small, cool, low-mass dwarfs. The Sun is larger, hotter, and more massive than these. There are stars that are much larger, very hot, and many times more massive than the Sun. But these stars are quite rare compared to the Sun or the lowmass stars. The Sun is also not ...
