Transcription: The outer gas giants, by contrast, have large diverse systems of satellites that resemble small solar systems. Jupiter has four particularly large moons, called the Galilean satellites, including the largest satellite in the solar system, Ganymede. Saturn has only one very large moon, Titan, which has a thick atmosphere of organic compounds. Saturn, however, with at least 22 moons, has the largest system of satellites of all the planets.
