A red dwarf is the least massive, smallest, least luminous, and coolest kind of star on the main sequence. Red dwarfs are by far the most common type of fusing star in the Milky Way, at least in the n
K-type main-sequence star
…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. K-type main-sequence stars have masses between 0.6 and 0.9 times the mass…
