22577 Alfiuccio ( provisional designation 1998 HT51) is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 2.4 kilometers in diameter. It was discovered on 30 April 1998, by the Lowell Observatory Near-Earth-Object Search at Anderson Mesa Station in Flagstaff, Arizona, United States. [5] It was named in memory of Alfio Grasso, an Italian boy from Sicily. [2]
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]
The asteroid's observation arc begins 20 months prior to its official discovery observation, with a precovery taken at the Chinese Xinglong Station in December 1996. [5]
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]
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]
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]
