I have always been curious how gravity alone could keep Jupiter moving in an orbit. As big and heavy as that rascal is, it looks like it would just fly right off at a right angle to its nanosecond-prior position.

So supposedly space is distorted and the big guy just kinda wallows around and rolls around an indentation, or warp caused by the heavier sun. But the sun is moving too, so how does the warp move so durn fast?

The heavier it is, the stronger gravity acts on it. There is just enough gravity to balance the centripetal force. Ko-inky dink?
