7556 Perinaldo           Discovered 1982 Mar. 18 by H. Debehogne at the European Southern Observatory.
Perinaldo is a village in Liguria, Italy, where the astronomer Giovanni Domenico Cassini (1625-1712) was born. A well-organized group of amateur astronomers in Perinaldo is today very active in the popularization of astronomy. The name was suggested by M. Di Martino.
