Update on the Planet Situation

[miss_yt]

So, apparently we now have twelve planets in our solar system: Ceres, formerly considered a large asteroid, residing between Earth and Jupiter; Charon, formerly considered to be a moon of Pluto but in truth engaged in a sort of roundabout with it; and Xena, out beyond Pluto.

Here's an article with a chart showing the new planets.

I hope they don't decide to add anything else before this settles down: I can remember three extra planets but too many more than that would be taxing.

Now...how do we develop a mnemonic device to remember these new planets? Especially since the last one starts with an X? Unless the mnemonic is based on Xena: Warrior Princess.
