.....But Saturn doesn't have a rocky core. It has a solid core, that's not the same thing. We're not even sure it's even solid at all, really. But if it is, it's made of frozen gas, silicates, and liquified nickel, pressurized so much from the weight of the gases above that it's been forced into one solid mass. It certainly wouldn't look like an ordinary rock like you show here.
