6882 Sormano (prov. designation: Шаблон:Mp) is an stony Eunomia asteroid from the middle region of the asteroid belt, approximately Шаблон:Convert 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]

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 Шаблон:Mp 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 Шаблон:MoMP was published by the Minor Planet Center on 3 May 1996 (Шаблон:Small).[4]

Physical characteristics

Rotation and shape

In September 2010, a rotational lightcurve of Sormano was obtained from photometric observations made at the Palomar Transient Factory in California. It gave a rotation period of Шаблон:Val hours with a high brightness variation of 0.71 magnitude, indicative of a non-spheroidal shape (Шаблон:Small).[5] A similar period of 3.998 hours was derived from remodeled data of the Lowell photometric database (Шаблон:Small).[6]

Diameter and albedo

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Sormano measures 7.6 to 8.0 kilometers in diameter and its surface has an albedo between 0.269 and 0.300.[7][8] The Collaborative Asteroid Lightcurve Link assumes an albedo 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 6.69 kilometers with an absolute magnitude of 13.19.[9]
