Alfiuccio is a member of the Flora family, one of the largest families of stony asteroids. It orbits the Sun in the inner main-belt at a distance of 1.9–2.6 AU once every 3 years and 6 months (1,266 days). Its orbit has an eccentricity of 0.15 and an inclination of 4° with respect to the ecliptic.[1]
In December 2010, a rotational lightcurve of Alfiuccio was obtained from photometric observations in the R-band at the Palomar Transient Factory, California. Lightcurve analysis gave a rotation period of 4.3704 hours with a brightness variation of 0.36 magnitude (U=2).[4]
Diameter and albedo estimate
The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 – derived from 8 Flora, the largest member and namesake of its orbital family – and calculates a diameter of 2.4 kilometers, based on a weaker absolute magnitude of 15.27.[3]
Naming
This minor planet was named in memory of Alfio "Alfiuccio" Grasso (1992–2004) who died in a hunting accident on the slopes of Mount Etna, Italy. The body's name was proposed by C. Blanco and M. Di Martino.[2] The official naming citation was published by the Minor Planet Center on 6 August 2009 (M.P.C. 66725).[6]
