    3176 Paolicchi, provisional designation 1980 VR1, is a carbonaceous asteroid from the outer region of the asteroid belt, about 34 kilometers in diameter. It was discovered on 13 November 1980, by Serbian astronomer Zoran Knežević at the Konkoly Observatory's Piszkéstető Station northeast of Budapest, Hungary.[7]

    The dark C-type asteroid orbits the Sun at a distance of 2.8–3.0 AU once every 4 years and 11 months (1,781 days). Its orbit is tilted by 18 degrees to the plane of the ecliptic and shows an eccentricity of 0.03. It has a rotation period of 20.400 hours[6] and an albedo in the range of 0.04–0.08, according to the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission.[1][4][5] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.05.[3]

    The minor planet was named in honor of Italian astrophysicist Paolo Paolicchi (b. 1950) at the University of Pisa, whose research activity included the study on the dynamical and collisional history of Small Solar System bodies and the origin of planetary and stellar systems. Paolicchi's work on minor planets has focused on the modeling of catastrophic breakup events and on the evolution of their rotational properties.[2]
