The outer planets exhibit a characteristically slow revolution around the Sun. They have varying rotation speeds, with Jupiter rotating quickly while others rotate more slowly. The key motion descriptor for all outer planets is their slow revolution relative to the inner planets. ;
The outer planets, including Jupiter, Saturn, Uranus, and Neptune, exhibit a slow revolution around the Sun, taking significantly longer to complete orbits compared to the inner planets. While their rotation speeds vary, with some like Jupiter having fast rotations, the defining characteristic is their slow revolution. Therefore, the correct answer from the options provided is B. fast rotation, slow revolution .
