It's Not Going to Work

So, scientists want to add three planets to our solar system. And they're even thinking of expelling Pluto from it.

Look, I'm not in elementary school any more. I no longer have anyone forcing me to memorize new planets. Don't change the solar system!!! I have the nine memorized and I still am not sure what order the first two are in. The rest I think I know. Anyway, the point is, right now I can name all nine, but if you add three more and possibly drop Pluto, I can't make any guarantees.
