Stars Grouped by Size

Supergiants are the largest stars, and may have diameters several hundred times the size of the Sun.

Giants are more common than Supergiants, and have diameters 10 to 100 times as large as the Sun.

Red Giants have cooler temperatures than giants, and are thus less bright, but their size is still massive.

Medium-size or dwarf stars are about as large as the sun.

White dwarfs are small stars (smaller than the distance across Asia).
