6882 Sormano (prov. designation: 1995 CC1) is an stony Eunomia asteroid from the middle region of the asteroid belt, approximately 7 kilometers (4.3 miles) in diameter. It was discovered on 5 February 1995, by Italian amateur astronomers Piero Sicoli and 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]
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]
Naming
This minor planet was named in honor of the Italian mountain-village of Sormano and its discovering nearby observatory. It is funded, built and operated by the "Gruppo Astrofili Brianza", a group of Italian amateur astronomers who have discovered numerous minor planets.[2] The official naming citation was published by the Minor Planet Center on 3 May 1996 (M.P.C. 27130).[9]
