"Rotating is a fundamental behavior of objects in the universe," Naoz said.Īsteroids rotate. In the case of Uranus, scientists have suggested that collisions - one huge crash with a big rock or maybe a one-two punchwith two different objects - knocked it off kilter, Scientific American reported.ĭespite these kinds of disturbances, everything in space rotates in one direction or another. A 2001 study published in Nature suggested that gravitational interactions with the sun and other factors might have caused Venus' spin to slow down and reverse. Over time, the sun's gravitational tug on Venus' thick clouds, combined with friction between the planet's core and mantle, caused the spin to flip. Or maybe it began rotating just like the other planets. For Venus, maybe a collision caused its rotation to flip. Scientists aren't sure how these planets got this way, but they have some ideas. Venus rotates in the opposite direction as Earth, and Uranus' spin axis is inclined 90 degrees. Today, however, some planets have put their own spin on their motion.
