My Very Earnest Mother...is confused.

I know I've got a number of school teachers and kids' librarians on my friends list, so I thought maybe you'd know. What's the order they teach for the planets these days? Is Pluto still in there, and if so, do I recall right that its orbit is inside Neptune's right now and so is the order switched? Is Eris in there? Is there a new mnemonic?

Rhys asked me yesterday and I realized I wasn't quite sure.

Thanks.
