Giovanni Cassini discovered the four Saturn moons Iapetus, Dione, Rhea and Tethys between 1671 and 1684. This astronomer also discovered that Saturn’s ring system has gaps. However, Christiaan Huygens discovered the first moon of Saturn called Titan in 1655. In 1789, William Herschel found two moons called Mimas and Enceladus.
Saturn has 62 moons, of which 53 are officially recognized moons while the rest are provisional. Titan is the largest moon, and two of the smallest moons are Telesto and Calypso. Most of Saturn’s moons have names that come from either Greek or Roman mythology. For example, Calypso was the name of a sea nymph in Greek mythology.
Saturn is an outer planet. Saturn’s atmosphere consists mainly of hydrogen and helium. This planet also has more than 30 rings.
