Star in the constellation Perseus
3 Persei is a single,[ 7] star in the northern constellation of Perseus . It is dimly visible to the naked eye under good viewing conditions, having an apparent visual magnitude of 5.70[ 2] parallax shift of mas
This star has a stellar classification of K0 IV,[ 3] K-type subgiant – an evolved star that has used up its core hydrogen and is evolving to become a red giant . However, da Silva et al. (2015) categorized it as a giant star proper.[ 8] mass of the Sun and has expanded to move than 8 times the Sun's radius . It is radiating roughly 37 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,757 K.[ 5]
