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 by German astronomer Max Wolf at Heidelberg Observatory on 20 September 1903.[8]
The minor planet orbits the Sun at a distance of 1.8–2.7 AU once every 3.38 years (1,234 days). Its orbit shows an eccentricity of 0.19 and is tilted by 5 degrees to the plane of the ecliptic. The S-type asteroid has an albedo of 0.20[4] and a rotation period of 3.42 hours.[5][7]
It was named after Mary Joan Wesson Bardwell, wife of Conrad M. Bardwell (1926-2010), after whom the minor planet 1615 Bardwell is named. He also established the identifications for this minor planet.[2]
