G star cooler than G2 5000 to 6000 K yellowish late star Yellowish star in which the H and K lines of Ca II have become dominant and in which a tremendous profusion of spectral lines of both neutral and ionized metals, particularly iron, begins to show. The Balmer lines of hydrogen are still recognizable. Examples are the Sun and Capella.

giant greater than 1000 Kelvin star High-luminosity star that lies above the main sequence on the Hertzsprung-Russell diagram. III

naked eye star Milky Way greater than 1000 Kelvin for many centuries asterism naked eye object brighter than 5 A star visible without visual aids

Capella 05 16 41.3 G5IIIe+G0III +45 59 53 Milky Way 5000 to 6000 K 104.023 days naked eye star 0.08 yellowish for many centuries 0.80 13 pc asterism brighter than 5 Alpha Aurigae The sixth brightest star in the night sky, consists of two yellow giants. A spectroscopic triple (F8-G0 III, G5 III, M5 V) (1974 parallax 0'.079). It has a high lithium content and a nearly circular orbit. It may be an X-ray source. III
