 * - Saturn is the 6th and the Second largest planet in ou solar system with a diameter of 120,536 km [Excluding the rings]**
 * - It is visible by the naked eye at night though it is not as bright as Jupiter**
 * - 10,759 Earth Days (about 29 1/2 years) to finish one revolution around the Sun with a speed of 9.69 km/s**
 * - Galileo Galilee was the first to observe Saturn was the aid of a telescope in 1610**
 * - Galileo first though the rings of Saturn were two moons beside the planet.**
 * - Cassini uncovered the gap in Saturn’s ring, later named the Cassini Division, and he found 4 more moons, which are Iapetus, Rhea, Tethys, and Dione. The NASA’s Pioneer 11 was the first spacecraft to visit Saturn, getting within 20,000 km of the planet’s cloud layers.**
 * - In Roman Mythology, Saturn is the god of agriculture and harvest.**
 * - Known as Roman God of Peace**
 * - Second largest planet in our solar system**
 * - Has a diameter of 364,900 km from the one edge of the ring to another (~9.44 times bigger than Earth)**
 * - It is a massive planet that 764 Earths can fit into it**
 * - 75% hydrogen and 25% helium with traces of water, methane, ammonia, crystals, and gases as ethane, phosphine**
 * - Rocky Core, liquid metallic hydrogen layer and a molecular hydrogen layer. Traces of various ices**
 * - Gaseous Planet, but not entirely**

 * - Composed of a series of disks orbiting around the planet with gaps in between**
 * - The planet is surrounded by clouds**
 * - The Upper layer composed of > ammonia ice clouds > temperatures can reach as low as -250° C.**
 * - The Lower Layer > a lower deck of ammonium hydro-sulfate clouds > with average temperatures rising to -70° C.**
 * - The lowest layer is made up of water clouds > mean temperatures here are at the freezing point of water – zero degrees Celsius.**
 * - Red Spot in the centre**
 * - Lowest Density (Can float on water)**
 * - Storms**
 * - No Solid Surface on Saturn**
 * - Where the rings came from**
