This is the second biggest
in our solar system and the only planet whose average mass does not exceed that
of water so if there is a sea that surround Saturn could soar.
At Saturn from a modern
telescope in 1610, Galileo draw it as a globe bounded by two smaller ones as a
head with large ears (the first one who came up with the Mickey Mouse logo).
Galileo thought it was moons but when two years later reviewed the planet had
disappeared. Later in 1655 the Dutch astronomer Christian Huygens discovered
Saturn having had a satellite orbiting Titan, announced that the planet should
be surrounded by an equatorial ring.
