58 Persei is a binary[3] and possibly a triple[13] star system in the northern constellation of Perseus. It has the Bayer designation e Persei, while 58 Persei is the Flamsteed designation. This system is visible to the naked eye as a faint point of light with an apparent visual magnitude of 4.26.[2] It is approximately 800 light years away from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +10 km/s.[4]

This is a single-lined spectroscopic binary system with an orbital period of 28.7 years and an eccentricity of 0.65.[14] The primary member, designated component A, is an orange-hued (K–type) bright giant with a stellar classification of K1II.[3] The star is around 50 million years old[7] with 6.8 times the mass of the Sun.[7] Having exhausted the supply of hydrogen at its core, it has expanded to roughly 87 times the Sun's radius.[8] It is radiating 1,731 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,500 K.[9]

The secondary, component B, appears to be a B-type main-sequence star with a stellar classification of B7V.[3] It is a suspected binary of unknown period with component masses of 3.3 and 1.2 times the mass of the Sun.[13]
