The Pleiades are among those objects which are known since the earliest times. At least 6 member stars are visible to the naked eye, while under moderate conditions this number increases to 9, and under clear dark skies jumps up to more than a dozen.
Cecilia Payne-Gaposhkin mentions that the Pleiades contain some wite dwarf stars. New observations of the Pleiades in 1995 have revealed several candidates of an exotic type of stars, or starlike bodies, the so-called Brown Dwarfs.
