"In our Solar System Saturn is the sixth planet from the Sun and the second largest planet after Jupiter in the solar system. It is a gas giant with an average radius about nine times that of Earth and the distance between Sun and Saturn is over 1.4 billion kilometers. With an average orbital speed of 9.69 km/s, it takes Saturn 10,759 Earth days or about 29½ years to finish one revolution around the Sun. Saturn is probably best known for the system of planetary ring that make it visually unique. That consist of nine continuous arcs, composed mostly of ice particles with smaller amount of rocky debrits and dust. The ring extended from 6,630 km to 12,700 km above to Saturn's equator average approximately 20 meters in thickness and are composed of 93% water ice within traces of thalin impurities and 7% amorphous carbon. The particles that make up the rings range in size from speck of dust up to 10m.

Although, the reflection of the rings increases Saturn's brightness they are not visible from Earth with unaided vision. In 1610, the year after Galileo Galilee first turned a telescope to the sky, he became the very, first person to observe Saturn's ring though he cannot see them well enough to discern their true nature. In 1655, Christiaan Huygens was the first person to describe them at disk surrounding Saturn. Although many people think of Saturn's ring being made so up of the as an annular disk with concentric local maxima and minima in density and brightness. On the scale of the clumps within the ring there are many empty Spaces.

The ring have numerous gaps where particle density drops sharply two opened by known moons embedded within them, and many other gaps remain unexplained stabilizing resonances on the other hand are responsible for the longevity of several rings such as the Titan Ringlet and the Q Ring.
Well beyond the main ring is the Phoebe ring, which is tilled at angle of 270 to the other rings and like Phoebe, orbits in ret rograte fashion.

In December 2010, National Geographic struggle that the rings of Saturn could be the remains of a giant lost moon that was stripped of its lay shell before it crashed into the planet.

I want to see the Cassini to take the pictures of rings of Saturn. I am sure it will reveal truth and open new door about new moons, Encke gap and ring’s material .I want to swim in the rings of Saturn to fulfill my dream with help of Cassini pictures."
