3951 Zichichi, provisional designation 1986 CK₁, is a stony Florian asteroid and binary system from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 12 February 1986, by staff members at the San Vittore Observatory near Bologna, Italy, and named after physicist Antonino Zichichi.

Orbit and classification

Zichichi is a S-type asteroid and member of the Flora family, one of the largest collisional populations of stony asteroids in the main-belt. It orbits the Sun in the inner main-belt at a distance of 1.9–2.7 AU once every 3 years and 7 months (1,307 days). Its orbit has an eccentricity of 0.17 and an inclination of 5° with respect to the ecliptic.

Physical characteristics

A minor-planet moon was discovered orbiting at a distance of 16 km in 2006, but not announced until 2011.

Naming

This minor planet was named after Italian nuclear physicist Antonino Zichichi. The approved naming citation was published by the Minor Planet Center on 20 May 1989 (M.P.C. 14634).
