58 Andromedae, abbreviated 58 And, is a single[9] star in the northern constellation Andromeda. 58 Andromedae is the Flamsteed designation. It is visible to the naked eye with an apparent visual magnitude of 4.78[2] The distance to this star, as determined from its annual parallax shift of Script error: No such module "val".,[1] is 186 light years. 58 And is moving further from the Earth with a heliocentric radial velocity of +8 km/s.[2] It has a relatively high proper motion, traversing the celestial sphere at the rate of Script error: No such module "val". per year.[10]

This star is 425 million years old with a stellar classification of A5 IV-V,[3] indicating the spectrum displays mixed traits of an A-type main-sequence star and an older subgiant star. It is spinning rapidly with a projected rotational velocity of 135 km/s, which is giving the star an oblate shape with an equatorial bulge that is 6% larger than the polar radius.[7] The star has double[4] the mass of the Sun and about 1.9[5] times the Sun's radius. It is radiating 36[2] times the Sun's luminosity from its photosphere at an effective temperature of 8,875 K.[4]
