Pluto has its moon, Charon, discovered in 1978. It also has two smaller ones found last year. Still, having gravitationally-bound satellites isn't enough to make it a planet... there are asteroids which would fit that bill. In all, Pluto just looks more like a member of the Kuiper belt family than it does a member of the eight inner planets.
The astronomical association has yet to rule one way or another but I'm coming to terms with the probability that Pluto will some day be officially downgraded like GM junk bonds.
