In 1610 Galileo was the first person to see Saturn through a telescope. Its shape puzzled him, because it didn’t look spherical, but looked more like an oval. In 1655, Christiaan Huygens had a better telescope and could see the rings more clearly. Two decades later, Giovanni Cassini made the discovery that the rings were not solid, but made up of particles. He also saw that there was more than one ring, and there was a large gap, 2980 miles wide, between two of them. The gap was called the Cassini Division, named in his honor.

The sixth planet from the Sun and the second largest, with a diameter about ten times that of Earth. Saturn is a gas giant that is almost as large as Jupiter in diameter but with only about 30 percent of Jupiter's mass. Its mainly gaseous composition together with its rapid axial rotation (it rotates once every 10.7 hours) cause a noticeable flattening at the poles and a prominent equatorial bulge. Saturn is encircled by a large, flat system of rings made up of rock fragments and tiny ice crystals, first observed by Galileo in 1610. The rings are believed to be unstable and therefore likely of recent origin; they may have been formed from bodies such as asteroids or moons that were shattered as they approached closer than the Roche limit . Saturn has numerous moons, of which the largest is Titan, the second largest moon in the solar system after Jupiter's Ganymede and larger than both Mercury and Pluto.

The Cassini-Huyggens spacecraft was launched in 1997 as a joint effort between the National Aeronautics and Space Administration (NASA), European Space Agency (ESA), and Italian Space Agency (ASI) to study Saturn and two of its moons. It reached Saturn in 2004 and captured photographs. The probe went on to study Titan, one of Saturn’s moons. In 2008, NASA extended the mission and renamed it the Cassini Equinox Mission. In 2010 the mission was called the Cassini Solstice Mission and will continue through 2017.
