Ok, this is a friendly, but ongoing argument my SO and I have been having. I contend that Saturn must
have some sort of rocky core because what else kept all the gases in place to create the planet? I will accept that the core may be in a molten state, but I think there must be something other than just a big ball of gas. My SO disagrees. :) He insists that it is a gas planet and that there are different types of gases and some strong enough to create a sort of gravity field that holds it all together.
As you can see, neither of us are scientists! And although I concede that he probably knows more about this type of thing than I do, I still think I could be right. But although I thought this would be easy enough to confirm from actual scientific data online, the only thing I've found so far is this from the Wikipedia posting: The interior of Saturn is probably composed of a core of iron, nickel, silicon and oxygen compounds
. Of course, my SO argues that this is one person's theory on Wikipedia, which doesn't count; and says that even if that is true, it could be the gas form of those compounds.
Surely there is a mefite with astronomical knowledge that could decide this argument for us. So which is it? Does Saturn have some type of rocky core or is it entirely made of gas?
