Main Question or Discussion Point
How is it possible for one planet to rotate opposite the others and one to rotate 90 degrees axially from the others, and these continue to rotate without stopping?
The rotation is affected by the gravity of other planets. Take Jupiter when it passes near the earth's rotation it affects the tides just like the Moon with its immense gravity even over long distances.the rotation of a planet is not affected by other planets
But not very much or they would all be tidally locked together.The rotation is affected by the gravity of other otat. r
you mean less intense. the quicker you zip by a mass, the less acceleration you feel due to that mass overallbut the gravity of other planets would be more intense because the planet passes by the other planets more quickly.
