8 Ιουνίου 1625: Giovanni Domenico Cassini

Giovanni Domenico Cassini, (1625-1712), was an Italian-born French astronomer who discovered four moons of Saturn and a large gap in Saturn's ring system. The gap is now known as the Cassini division. Cassini is also known by the French name Jean Dominique Cassini. Because of his discoveries pertaining to Saturn, a space probe that the United States launched in 1997 to investigate that planet was named after him.
