It's all about time, The planets orbits are changing as we speak, we just can't tell, in a million years or so things will be different, you gotta think about time on a cosmic level, a few million years ago there was so much colliding going on, it was like a war zone, but over time, they've fallen into they're set paths and most of the debree has been swept up and we won't experience that much action.

They wobble. There's a thing called the "Disturbing Function" (no, really) which allows you to calculate the perturbations to orbits.
The solar system can really be considered as a two body problem (the Sun and Jupiter) with perturbations (the other planets).
But basically, the main gravitational pull in the solar system comes from the Sun. By comparison, the effect of, say, Mars on Earth is negligible, which is why it can be considered as just a perturbation.

They do. That's why Uranus is on its side and how Earth's moon was formed. All of this was sorted out billions of years ago. The remaining planets are on a relatively stable orbit because the planets are so far away from each other that their gravitational pull among each other is minimual.

Though mankind is much advanced in scientific findings, our knowledge about universe is very little. No scientific reason could ever been found on why and how planets are orbiting and are not colliding each other. Various answers given above are imaginary and vague.

There is a less popular theory that say the the Asteroid belt is the remains of a collision. So, I believe that planets and other things do collide.

we people to have gravitational pull according to our weight but it is so less that we do not get attracted to each other & the gravitational pull of earth is far more than any other pull on earth so we mainly get attracted towards earth
similarly the grvitational force of the sun is stronger so it rules like the head of the family and controls them fom colliding into each other

The sun hold the planets in their orbits.Its like launching a satellite into the atmosphere & have it settle into its orbit.The present arrangement of solar system is stable.

They are many millions of miles apart and have been in stable orbits for billions of years.
