58 Persei is a binary [3] and possibly a triple [12] 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. [13] 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 [7]  million years old with 7 [7] times the mass of the Sun. Having exhausted the supply of hydrogen at its core, it has expanded to roughly 56 [8] times the Sun's radius. It is radiating 1,698 [5] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 5,173 K. [7]

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. [12]
