    13058 Alfredstevens, provisional designation 1990 WN3, is a stony Vestian asteroid from the inner regions of the asteroid belt, about 3 kilometers in diameter. It was discovered by Belgian astronomer Eric Elst at ESO's La Silla Observatory in Northern Chile, on 19 November 1990.[5]

    Based on its orbital elements, the S-type asteroid is a member of the Vesta family, a group of asteroids that originated from a massive impact on the Southern Hemnisphere of 4 Vesta, the family's namesake. It orbits the Sun at a distance of 2.1–2.6 AU once every 3 years and 7 months (1,323 days). Its orbit shows an eccentricity of 0.12 and is tilted by 6 degrees to the plane of the ecliptic.

    A photometric light-curve analysis at the Palomar Transient Factory Survey rendered a rotation period of 4.3 hours with a brightness amplitude of 0.0057 in magnitude.[4] It has an albedo of 0.20, as assumed by the Collaborative Asteroid Lightcurve Link.[3]

    The minor planet was named in honour of Belgian painter Alfred Stevens (1823–1906), known for his paintings of elegant modern women.[2]
