K-Type Star

(K)
(type of star with about 3/4 the mass of the Sun)

A K-Type Star is a star of the K-Class, a Spectral Class for stars of around .75 Solar Mass and .75 solar radius. They burn up their Hydrogen in tens of billions of years. They have very weak hydrogen lines. Characteristics:

K-type stars are a good bet for habitable Extra-Solar Planets, but offer few planets for study because the stars are much rarer than M-Type Star and much dimmer than the hotter classes.
