Saturn is more impressive than Earth in many ways. For example, while Earth has only one moon, Saturn has more than 150 moons. Saturn also has rings that stretch out tens of thousands of miles away from the planet and are mostly made up of chunks of ice and dust.
Scientists have learned a lot about Saturn because it has been visited four times. The Pioneer 11, Voyager 1, Voyager 2 and Cassini-Huygens spacecrafts have all sent valuable information about Saturn's atmosphere back to Earth. While there has been some discussion about humans inhabiting Mars, there is less discussion about humans being able to live on Saturn; the planet is extremely cold and has poisonous gas in its atmosphere, making it impossible for a human being to survive there. It also would take at least three years for a spacecraft to arrive at Saturn after leaving Earth.Learn more about Planets
