Protobon:

That is not a question that can be explained on the basis of planet rotations. Jupiter rotates as a normal part of the system. Venus does not. I think it is obvious that Venus was flipped over in the past giving us what we see now. In possibly 90 years from now Venus will return to a naturally rotating object, it will cool down and it will be on its way to becoming the newist tourist attraction. Don't hold your breath.
