K-type main-sequence star

A K-type main-sequence star (also called a "K-type dwarf" or "orange dwarf") is a main-sequence (core hydrogen-burning) star of spectral type K. The spectral luminosity class is V. These stars are intermediate in size between red dwarfs and yellow dwarfs, hence the term orange dwarfs often applied to this type. == Description == K-type main-sequence stars have masses between 0.6 and 0.9 times the mass of the Sun and surface temperatures between 3,900 and 5,300 K. These stars are of particular interest in the search for extraterrestrial life due to their stability and long lifespan.
