hope that helped

Well, since Pluto's demotion, the solar system only has
eight (8) official planets, so there's no official answer to
your question.

To some dinosaurs like me, when we talk about the solar system
without Pluto, it always feels as though something important is missing. 
If you still hold on to Pluto, and still consider it to be a planet no matter
what those who know what they're talking about are saying, then Pluto
is your ninth planet closest to the Sun.
