Not really and they have different speeds of rotation. I found a pretty good explanation on one space forum.
The closer a body gets to a massive object (Sun) the faster it travels. It's similar to how a magnet works, the closer iron is to a magnet the harder it's pulled toward it.
We call this action of attraction for planets and such "gravity" but we don't fully understand just what it is. But we do know to an exact degree how it behaves.
Since objects in freefall will travel much faster near the Sun then they would only avoid crashing if they orbit much faster than those objects far from the Sun.
