}}'''Hyperion''', or '''Saturn VII''', is the eighth [[moon]] of [[Saturn]] to be discovered, and the largest irregularly shaped body in the [[Solar system]]. ([[Proteus]], moon of [[Neptune]], is heavier but has a more nearly spheroid shape.) It is also highly porous, having the appearance of a [[sponge]], and displays a chaotic rotation.

Hyperion has an irregular shape, with dimensions 185 x 140 x 113 km.<ref name=saturnsatfact/> In fact it is the largest irregularly shaped body in the solar system. [[Proteus]], moon of [[Neptune]], is often cited as a larger irregular body, but in fact Proteus is not irregular and is almost spherical.<ref name=Arnett/> Hyperion is also highly porous, with a density only 57% of that of [[water]].<ref name=saturnsatfact/>
