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 (F), a G-Type Star (G), or a K-Type Star (K). 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.
