Supporting sentence: Saturn is a massive ball made mostly of hydrogen and helium. It's surrounded by a beautiful ring system. It's the farthest planet from Earth discovered by the unaided human eye.

Supporting sentence: One day on Saturn takes only 10,7 hours (the time it takes for saturn to rotate or spin around once), and Saturn makes a complete orbit around the sun (a year in Saturnian time) in about 29,4 Earth years (10,756 Earth days).

Supporting sentence: Saturn rings are thought to be pieces of comets. The ring particles are as large as mountains. The rings would look mostly white if you looked at them from the cloud tops of Saturn, and interestingly, each ring orbits at a different speed around the planet.

Supporting sentence: At Saturn's center is a dense core of metals like iron and nickel surrounded by rocky material and other compounds solidified by intense pressure and heat. It is enveloped by liquid metallic hydrogen inside a layer of liquid hydrogen -similiar to Jupiter's but considerably smaller.

Supporting sentence: The planet is mostly swirling gases and liquids deeper down. While a spacecraft would have nowhere to land on Saturn, it wouldn’t be able to fly through unscathed either. The extreme pressures and temperatures deep inside the planet would crush, melt, and vaporize any spacecraft trying to fly into the planet.

Supporting sentence: Winds in the upper atmosphere reach 1,600 feet per second (500 meters per second) in the equatorial region. In contrast, the strongest hurricane-force winds on Earth top out at about 360 feet per second (110 meters per second). And the pressure – the same kind you feel when you dive deep underwater – is so powerful it squeezes gas into a liquid.Saturn's north pole has an interesting atmospheric feature – a six-sided jet stream.
