A K-type main-sequence star, also referred to as a K dwarf or Orange dwarf, is a main-sequence (hydrogen-burning) star of spectral type K and luminosity class V. These stars are intermediate in size between red M-type main-sequence stars ("red dwarfs") and yellow G-type main-sequence stars. They have masses between 0.5 and 0.8 times the mass of the Sun and surface temperatures between 3,900 and 5,200 K. These stars are of particular interest in the search for extraterrestrial life. Well-known examples include Alpha Centauri B (K1 V) and Epsilon Indi (K5 V).
