8 - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Almost assurdly there are no more big ones. There are also a class of planets called "dwarf planets", including Pluto and a couple of others.

I say nine. I don't like the idea of relegating Pluto just because it is so much smaller and of different origin to the other 8. For the last 80 years we have had 9, and I think an exception should be made for Pluto, although the new minor planets that keep being discovered should not be full planets, even if they are bigger than Pluto.
There we go. Interplanetary rant over with.

Eight. There were nine before Pluto got demoted. There are several other planetary bodies, whose discovery precipitated the review of what it meant to be a planet.

Just 8 officially: Pluto got axed as a planet and relocated as a planetesimal. Unofficially nobody knows for sure.

8, but some scientists are still argueing. So in the future there could be more.
