Saturn is a gas giant. Interestingly it is composed of many of the same elements that make up the sun consisting of mostly hydrogen and helium. Saturn's core is liquid metallic hydrogen.
There is pre-diluvial legend that Saturn was indeed illuminated at some point in the past which is why it was (and continues to be) worshiped. Saturn is the keystone.
