Difference between Deferent and epicycle and Retrograde and prograde motion

Deferent and epicycle vs. Retrograde and prograde motion

In the Hipparchian and Ptolemaic systems of astronomy, the epicycle (from ἐπίκυκλος, literally upon the circle, meaning circle moving on another circle) was a geometric model used to explain the variations in speed and direction of the apparent motion of the Moon, Sun, and planets. 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).

Similarities between Deferent and epicycle and Retrograde and prograde motion

Deferent and epicycle and Retrograde and prograde motion have 8 things in common (in Unionpedia): Apparent retrograde motion, Ecliptic, Jupiter, Orbit, Planet, Sun, Uranus, Venus.

Apparent retrograde motion

Apparent retrograde motion is the apparent motion of a planet in a direction opposite to that of other bodies within its system, as observed from a particular vantage point.

Planet

A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.
