Description: A G star is one whose "surface" temperature (the temperature of the layer in the star from which its light is emitted also known as effective temperature) is between approximately 5200 and 6000 kelvins. A G star is identified by strong absorption lines from ionised calcium and strengthening atomic metals in its spectrum. G stars appear yellow to the human eye when viewed through the Earth's atmosphere. The Sun is an example of a G star.
