Which way will a planet spin if it forms in orbiting debris?

Question

If a small planetoid in a disk of debris is orbiting around or spiraling in on the Sun, the debris outside of it will be going slower than the planetoid and the debris inside the planetoid will be going faster. As the debris is drawn to the planetoid by gravity, will the incoming debris result in a planet that spins clockwise or counterclockwise and why? I don't have the Physics to evaluate the effects of the Sun's gravity pulling one way on the debris and the planetoid's pulling the other. We're looking down on the system from above of course.
I know that if the whole disk has the same angular velocity that the planet will end up spinning counterclockwise like we do.

Answer 1

OK... Let's look at the thesis statement.
1. A disk of debris: This implies that the debris is orbiting the planetoid. If this is so, then the speed of their orbit is regulated by their position relative to the planetoid rather than the Sun.
2. The planetoid has a history and in that history has acquired an angular momentum. That angular momentum will determine the original spin of the final planetoid after it has finished acquiring the debris.
3. The final spin will be determined by the distribution of mass within the planetoid and its distance to the Sun. If the mass is distributed homogeneously, then the original spin will be maintained. If the mass is distributed unevenly, then the Sun's gravity will eventually change the spin to match the gravity well of the nearest approach. If the orbit is nearly circular, then one side will face the Sun. The spin will be determined by the orbital direction the planetoid takes around the Sun. If the orbit is not nearly circular, the uneven distribution of mass will give the planetoid a gravity induced spin to match the direction of the orbit.

;-D Remember that drawing a 2 dimensional graphic to understand orbital mechanics is misleading. Everything is in free fall. Gravity rules. The Earth and the Moon for example orbit each other. It is just that the focal point is inside the Earth. It is convenient to draw the Earth in the center and the Moon circling around it. But both the Moon and the Earth are moving together through space and the Moon's actual path is a 3 dimensional spiral.

Answer 2

I think its due to a universal - gravitational "north". Or a mega correolus affect. Flush your toilet and the water always goes the same way. Its that on a universal scale.

Answer 3

Looking from the top, they always spin counterclockwise. Looking from the bottom they will spin clockwise. You can always tell if you looking from the top or bottom by the direction of spin.
