If everything started with the big bang and every object in the universe is moving away from every other object in all directions why does the earth stay the same distance from the sun and all the other planets in our solar system ?

Because they are bound together by gravity. Galaxies are similarly held together by gravity, And even clusters of galaxies.

It is only on very large scales (the distances between clusters of galaxies) that we can see expansion happening.
