Because they have separate, non-intersecting orbits. It's not as if they're all up there in a great big random cloud orbiting the sun.

Well, in fact, they *have*. A planet the size of Mars impacted the Earth about 4 billion years ago, the result of which turned out to be the moon.
The planets at present are spaced very far apart, and are in very stable orbits, separate from each other.

They're in stable orbits millions of miles apart. All the colliding that was going to happen probably happened billions of years ago.

In my professional opinion, they don't collide mostly because they are millions of miles away from each other in non-intersecting orbits.

Because the are SOooooo far apart. And their orbits are quite stable.

Because they tend to move in the same direction and different orbits.
