3 Persei is a single,[1] orange-hued 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] The star is located around Шаблон:Convert distant, based upon an annual parallax shift of Шаблон:Val.

This star has a stellar classification of K0 IV,[3] suggesting it is a 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.[4] At the age of around three billion years, it has an estimated 1.4 times the 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]
