FGK Star

(a star of class F, G, or K)

The name FGK Star is used to designate a star that is either an F-Type Star, a G-Type Star, or a K-Type Star. Since these are the Spectral Classes MOST like the Sun, it is plausible that life would be found in such a system. Some star Surveys cover this set of classes, especially those looking for Biosignatures.
