Retrograde Motion. Retrograde motion is the orbital motion of a spatial body in a direction that is opposite of what is normal in a given system. “Retrograde” is derived from the Latin words retro, backwards, and gradus, step. In the Solar system, all major planets orbit the Sun counterclockwise as seen from Polaris.
First, all planets (and asteroids) show prograde and retrograde motion. The duration of each part is dependent upon how far away it is in the solar system and whether it's inner to Earth (Mercury, Venus) or exterior. Also, most planets spend most of their time in prograde motion. Retrograde means it goes against the direction it normally goes.

In general, polar motion excitation shows two circular motions with opposite directions: clockwise, usually called retrograde, with frequency marked as negative, and counter-clockwise, named prograde, with frequency marked as positive [7,56,57].
