- A giant star has a substantially larger radius and luminosity than a main-sequence (or dwarf) star of the same surface temperature. They lie above the main sequence (luminosity class V in the Yerkes spectral classification) on the Hertzsprung–Russell diagram and correspond to luminosity classes II and III. The terms giant and dwarf were coined for stars of quite different luminosity despite similar temperature or spectral type (namely K and M) by Ejnar Hertzsprung in 1905 or 1906.

The Wonderful Wizard of Oz is a children’s novel written by L. Frank Baum and illustrated by W. W. Denslow. It was originally published by the George M. Hill Company in Chicago in 1900, and has since been reprinted countless times, sometimes under the name The Wizard of Oz. The story chronicles the adventures of a girl named Dorothy in the Land of Oz. It is one of the best-known stories in American popular culture and has been widely translated. Its initial success led to Baum’s writing and having published thirteen more Oz books.
