How Many Planets?

This afternoon on my KMOX show, Phil Plait discussed the "what's a planet?" controversy, whether Pluto will no longer be considered a planet, and whether other big rocks could be upgraded so that we have 12 planets in our solar system.

Listen to the conversation here.

Phil's Bad Astronomy Blog is here. His must-read book, "Bad Astronomy" has great info on debunking claims that the moon landing was a hoax, and on astronomy errors in science fiction movies.
