Category:Main Sequence K-type

A K-type main sequence star, also referred to as a K-type dwarf or an 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/white G-type main-sequence stars. They have masses between 0.6 and 0.9 times the mass of Sol 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. Well-known examples include Alpha Centauri B (K1 V) and Epsilon Indi (K5 V).
