Valter Giuliani at Sormano Astronomical Observatory in northern Italy.[1] The asteroid was named for the Italian mountain-village of Sormano and its discovering observatory.[2]
Orbit and classification
Sormano is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.3–2.8 AU once every 4 years and 1 month (1,489 days). Its orbit has an eccentricity of 0.10 and an inclination of 14° with respect to the ecliptic.[3] The asteroid's observation arc begins 6 years prior to its discovery, as it had previously been observed as 1989 OW at Palomar Observatory in 1989.[1]
