  description = """
  Saturn is the sixth planet from the Sun and the second largest in the Solar System,
  after Jupiter. It is a gas giant, with an average radius of about nine times that
  of Earth. It has an eighth the average density of Earth, but is over 95 times more
  massive. Even though Saturn is almost as big as Jupiter, Saturn has less than a third
  its mass. The planet has a bright and extensive system of rings, composed mainly of
  ice particles, with a smaller amount of rocky debris and dust.
