G class star

A G-class (or G-type) star is a stellar classification for stars composed of both neutral and ionized atoms of metallic substances, including ionized calcium, emitting in the neighborhood of 5,000 to 6,000 degrees Kelvin, generally referred to as being yellow in color. G-type stars in the main sequence tend to be median in terms of absolute magnitude, and in the "cooler" half of the stellar classification system. Yellow G-type stars can range in size from yellow giants to the more diminutive yellow dwarf. (Reference book: Star Trek: Star Charts)
