Nolan's class has been studying the solar system, and each student had to create a display of some sort to show the major planetary bodies, along with facts about each. Tomorrow they are putting on a play about the solar system. Nolan gets to be Planet X!
What's that little thing in the top-left corner of the planetary poster?
I hope that's not Pluto, which would be so pre-August 24, 2006!
Pluto's status was well-discussed at school -- Nolan opted to include it and label it as a dwarf planet.
