-Saturn seems to have a core between about 10 to 20 times as massive as Earth.
- Storms on Saturn can last for months or even years. A long-lived 2004 storm on Saturn, named the "Dragon Storm" created mega-lightning 1000 times more powerful than lightning on Earth.
-Saturn is the flattest planet: Its polar diameter is 90% of its equatorial diameter, this is due to its low density and fast rotation. Saturn turns on its axis once every 10 hours and 34 minutes giving it the second shortest say of any of the solar system's planets.
-Saturn orbits the Sun once every 29.4 Earth years: Its slow movement against the backdrop of stars earned it the nickname of "Lubadsagush" from the ancient assyrians. The name means "oldest of the old".
-Saturn is made mostly of hydrogen: it exits in layers that get denser farther into the planet. Eventually, deep inside, the hydrogen becomes metallic. At the core lies a hot interior.
-Saturn has 150 moons and smaller moonlets: All are frozen worlds. The largest moons are Titan and Rhea. Enceladus appears to have a an ocean below its frozen surface.
In Roman mythology, Saturn is the god of argriculture. The associated Greek god, Cronus, was the son of Uranus and Gaia and the father of Zeus (Jupiter). Saturn is the root of the English word "Saturday"
Saturn has been known since prehistoric times. Galileo was the first to observe it with a telescope in 1610; he noted its odd appearance but was confused by it. Early observations of Saturn were complicated by the fact that the Earth passes through the plane of Saturn's rings every few years as Saturn moves into orbit. A low resolution image of Saturn therefore changes drastically. It was not until 1656 that Christiaan Huygens correctly inferred the geometry of the rings. Saturn's rings remained unique in the known solar system until 1977 when very faint rings were discovered around Uranus (and shortly thereafter around Jupiter and Neptune).
