Saturn
Saturn is the second largest planet in the Universe, after Jupiter and it is named after the Roman God of agriculture. This planet is categorized with the gas giants. It has got a diameter of 120,536 km and it's mass is estimated at 5,685×10^26 kg, this is striking because the diameter is only about 9 times as big as Earth but its mass is about 95 times bigger. A year on Saturn takes 10,757.73 days on Earth which is 29,45 years on Earth. This planet is well-known because of it's rings, first they thought that those were the moons of Saturn but later was discovered that these were ice particles which orbit around Saturn. From Earth we can identify three rings those are called A,B and C. There are known 18 moons which orbit around Saturn, the biggest we know is Titan which has got it's own atmosphere and is bigger than the planet Mercury. The average temperature on the sun is -185 degrees celsius. The composition of the atmosphere of Saturn: 96.3 percent hydrogen, 3.25 percent helium, minor amounts of methane, ammonia, hydrogen deuteride, ethane, ammonia ice aerosols, water ice aerosols, ammonia hydrosulfide aerosols. Saturn is the least dense planet 0,687 g/cm^3 which is less than water, so theoratically: if there was a bathtub big enough for Saturn and you would fill it with water, Saturn floats on it. Sometimes you can see yellow-gold bands on Saturn, those are the result of some super-fast winds on the planet which can reach speeds up to 1800 km/h.
