Notes
Epsilon Geminorum. At Epsilon Geminorum's distance, extinction from interstellar dust is causing a magnitude reduction of 0.27.[7] The spectrum of this star matches a stellar classification of G8 Ib,[3] where the luminosity class of Ib indicates this is a lower luminosity supergiant star. Alternatively, it may be a star that has passed through the asymptotic giant branch stage and possesses a detached shell of dust.[19] It has 5.3 times the mass of the Sun and it is estimated to be 100 million years old.[8] Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified.
