Retrogade Motiondefinition from Wiki : direction opposite to the movement of something else, and is the contrary of direct or prograde motion. The idea of retrograde or prograde motion is useful in three contexts: (1) for describing the orbits of celestial bodies, (2) for describing the rotations of celestial bodies, and (3) for explaining the backtracking by planets which is visible to observers on Earth (See the article: Apparent retrograde motion).
