▲Saturn is an oblate spheroid, meaning that it is flattened at the [[pole]]s, and it swells out around its [[equator]]. The planet's equatorial [[diameter]] is 120,536 [[kilometre|km]] (74,867 [[mile|mi]]) whereas its polar diameter (ie. from the north pole to the south pole) is 108,728 km (67,535 mi); a 9% difference. Its flattened shape is due to its very fast rotation, rotating once every 10.8 Earth hours. Saturn is the only planet in the [[Solar System]] that is less [[density|dense]] than [[water]]. Even though the planet's [[planetary core|core]] is very dense, it has a gaseous [[atmosphere]], so its average [[relative density|specific density]] of the planet is 0.69 g/cm³ (less than water). As a result, if Saturn were placed in a large pool of water, it would float on it.
