There are no deep answers to the questions you're asking. There are no absolutes, there is no "plan" for you or me or anything. It just happened to be this way, might as well take advantage of it.
The solar system having 9 planets is actually up for debate right now. As it stands, if Pluto remains a planet then there are objects larger than pluto that have been discovered in the Keiper belt. These should also be classified as planets =P. Imagine if we crashed into one of those sons of bitches x_X.
Indeed, the current theory is that there were dozens and dozens of small planets that collided with one another. That is how the moon supposedly was made ...but there are objects larger than pluto which are comprised of rock =P. Did you see where it was decided? I was thinking it'd be newsworthy.
It's a planet because has rock in its centre? As in solid rock, or molten rock?
If molten rock, then I can understand why it's a planet, and bigger things in the Keiper Belt aren't... but if it's just rock, well, if that's the case then EVERYTHING, or at least most things, are planets.
