7866 Sicoli, provisional designation Шаблон:Mp, is a stony Nysa asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 13 October 1982, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona.[1] The asteroid was named after Italian astronomer Piero Sicoli.[2]
Orbit and classification
Sicoli is a member of the stony subgroup of the Nysa family, one of the smaller families in the main-belt, named after its namesake, 44 Nysa. The body orbits the Sun in the inner main-belt at a distance of 1.9–2.9 AU once every 3 years and 9 months (1,382 days). Its orbit has an eccentricity of 0.21 and an inclination of 3° with respect to the ecliptic.[3] The first precovery was taken at Palomar Mountain in 1954, extending the asteroid's observation arc by 28 years prior to its discovery.[1]
Physical characteristics
Diameter and albedo
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Sicoli measures 6.3 kilometers in diameter and its surface has an albedo of 0.246,[4][5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.21 and calculates a diameter of 5.6 kilometers, based on an absolute magnitude of 13.3.[6]
Lightcurves
As of 2016, no rotational lightcurve has been obtained for this asteroid and its rotation period and shape remain unknown.[3][6]
Naming
This minor planet was named in honor of Italian astronomer Piero Sicoli (born 1954), a discoverer of minor planets and Observation Coordinator at the Sormano Astronomical Observatory in northern Italy.[2] The official naming citation was published by the Minor Planet Center on 28 July 1999 (Шаблон:Small).[7]
