2017 Wesson, provisional designation A903 SC, is a stony asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 20 September 1903, by German astronomer Max Wolf at Heidelberg Observatory in southern Germany.[10] It was later named after Mary Joan Wesson Bardwell, wife of Conrad Bardwell, an associate director of the Minor Planet Center.[2]
Wesson orbits the Sun in the inner main belt at a distance of 1.8–2.7 AU, orbiting once every 3 years and 5 months (1,235 days). Its orbit has an eccentricity of 0.19 and an inclination of 5° with respect to the ecliptic.[1]
