2490 Bussolini (

Eunomia asteroid from the central region of the asteroid belt, approximately 12 kilometers (7.5 miles) in diameter. It was discovered on 3 January 1976, by staff members of the Félix Aguilar Observatory at El Leoncito Complex in Argentina.[7] The asteroid was named after Argentine Jesuit physicist Juan Bussolini.[2]

Classification and orbit

Bussolini is a member of the Eunomia family, a large group of typically stony asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.3–3.0 AU once every 4 years and 3 months (1,539 days). Its orbit has an eccentricity of 0.13 and an inclination of 13° with respect to the ecliptic.[1] A first precovery was taken at Palomar Observatory in 1949, extending the body's observation arc by 27 years prior to its official discovery observation at El Leoncito.[7]

Physical characteristics

Eunomians are typically S-type asteroid.[3] Bussolini has also been characterized as a P-type asteroid by the Wide-field Infrared Survey Explorer (WISE).[5]

Diameter and albedo

According to the surveys carried out by NASA's WISE observatory with its subsequent

albedo of 0.223 and 0.1918, respectively.[4][5] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 12.09 kilometers with an absolute magnitude of 11.9.[3]
