This document provides information about the gas giants Saturn, Uranus, and Neptune. It details facts about their distances from the sun, diameters, rotation and revolution periods, temperatures, atmospheres composed primarily of hydrogen and helium, and their moons. Saturn has over 50 moons, Uranus has 27 moons, and Neptune has 13 known moons. The document also notes that Uranus' axis is tipped over resulting in its poles lying on its sides.
