Giovanni Cassini

Giovanni Cassini was Italian-French astronomer who lived between 1625-1712. He discovered four of Saturn's moons, in addition to those found by Huygens.

Cassini also discovered that Saturn's Rings are split into two parts, and the gap between them is called the "Cassini Division".
