    The retrograde motion of a hypothetical extremely distant (and nearly non-moving) planet would take place during a half-year, with the planet's apparent yearly motion being reduced to a parallax ellipse. The center of the retrograde motion occurs at the planet's opposition which is when the planet is exactly opposite the Sun.

High-inclination asteroids are either Mars-crossers (possibly in the process of being ejected from the Solar System) or damocloids. Some of these are temporarily captured in retrograde resonance with the gas giants. [20]

As the Earth passes by a planet that particular planet appears to move backwards i.e. westward, amid the stars, this phenomenon is called retrograde motion, which motion invariably occurs at a time when that planet is visible for a relatively longer period. the approximate midpoint of which period in respect of the superior planets coincides with opposition ...
