Retrograde motion in astronomy is, in general, orbital or rotational motion of an object in the direction opposite the rotation of its primary, that is, the central object (right figure). It may also describe other motions such as precession or nutation of an object's rotational axis .
Asteroids and Kuiper Belt objects (including Pluto) exhibit apparent retrograde motion. This motion is normal for the planets, and so is considered direct motion. However, since Earth completes its orbit in a shorter period of time than the planets outside its orbit, it periodically overtakes them, like a faster car on a multi-lane highway.
A satellite with an orbital inclination between 90° and 180° (or, equivalently, between 0° and −90°) is said to be in a retrograde orbit. [note 2] A satellite in a direct orbit with an orbital period less than one day will tend to move from west to east along its ground track. This is called "apparent direct" motion.

When Neptune, planet of illusion, is in direct motion, we can be confused by our sentiments and emotions. When it is retrograde, the veil is lifted, and we can sort through our feelings.
Vakragati means retrograde motion. 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 ...
Apparent retrograde motion is the periodic, apparently backwards motion of planetary bodies when viewed from the Earth (an accelerated reference frame). Satellite is an object that orbits another object (known as its primary). The term is often used to describe an artificial satellite (as opposed to natural satellites, or moons).
Planets moving in direct motion, aka non-retrograde planets, act in a very predictable way without much fuss or fanfare. Most of the time, planets move in this forward motion, and things carry on ...
