hm .. there could be an infinite number of orbits around the sun. It's just the way things ended up I guess.

Actually the first answerer is sort of correct. The reason the remaining 9 [or 8 or whatever since the powers that be have re-defined what a planet is--guess this old dog has to learn a new trick after all] planets are the only ones left in orbit around our Sun is because they are the ones left over from collisions when the solar system formed. All the other bodies impacted with each other causing desctruction or rebounds out of safe orbits into either other bodies or out of the system istelf. Imagine a multilane highway where some of the lanes have vehicle collisions in them, the only lanes left with freely moving traffic will be the ones that don't have any obstructions. And, all the objects involved in the collsions will eventually be removed from the highway completely.

Well actually there are several "planets" in each orbit. It just depends on what you, or they define as a planet.
If you look outside tonight and see the big round thing in the sky that is revolving around our little planet..... It is also in the same orbit around the sun as we are. Same with the other planets in our solar system.
Kinda funny how that works huh?

because the orbit is defined by the path of a single planet :)

so they don't run in to each other and explode
