What is the difference between prograde rotation and retrograde rotation

Retrograde rotation is the motion of a body moving in the opposite direction of another body. Prograde rotation is a body moving in the same direction. Examples: sun moving in same spinning direction as another planet(prograde) Neptune moving in the opposite direction as earth as they revolve around the sun (retrograde)
