" ... The classification system of stars by color and magnitude is very useful. By surveying our local ... [+] region of the Universe, we find that only 5% of stars are as massive (or more) than our Sun is. It is thousands of times as luminous as the dimmest red dwarf star, but the most massive O-stars are millions of times as luminous as our Sun. About 20% of the total population of stars out there fall into the F, G, or K classes, but only ~0.1% of stars are massive enough to eventually result in a core-collapse supernova. ... "
