The document discusses the conditions on several planets that could potentially support human life including Saturn, Jupiter, Uranus, Neptune, and Mars. Saturn has the most spectacular rings in the solar system. Jupiter would be very cold at around 100 to 180 degrees Fahrenheit. Uranus has a unique tilted axis and methane atmosphere. Neptune is the farthest gas giant and takes over 30 times longer than Earth to orbit the sun. Mars has seasons and weather but its atmosphere is too thin to support liquid water on the surface for long.
