CHARACTERISTICS OF STARS
... The stars in the sky all appear to be points of light of the same size. Many stars are actually the same size of the Sun, which is a medium-sized star. However, some stars are much larger and are called giant and supergiant stars. Most stars are much smaller than the Sun. Black and white dwarf stars ...
