It isn't much of a debate now, but it centered on how to define the word 'planet'. The accepted definition ended up including a clause that a planet must dominate its orbit, which excluded bodies like Pluto. The alternative definition did not include this clause, and would have added at least 4 planets to the number then accepted.
