Question

describe the motion of the outer planet

Answer 1

Answer:

For the outer planets, Mars, Jupiter, Saturn, and so on, the explanation is a bit more subtle. These planets are further from the Sun than we are, and they orbit the Sun more slowly than we do. ... An outer planet's apparent motion is always retrograde for a month or more before and after opposition.
