Answer 1

The two phrases that best describe the motion of all the outer planets are:

**fast rotation, slow revolution.**

Outer planets typically have a relatively rapid rotation period (completing a rotation on their axis in a relatively short time) while having a longer orbital period around the Sun (which is referred to as revolution).
