How many planets are there anyway? A recent National Geographic competition seems to suggest that they think that the answer is 11. They're including Ceres, Pluto and Eris to the astronomers' canonical list of eight.
Our kids' books all still sport nine, so S1 thinks Pluto is a planet. I'm not brave enough to pit myself against a book. So, as far as he is concerned, there are nine planets.
