The two inner planets Mercury and Venus move in retrograde motion (east to west along the ecliptic) between their time of greatest distance from the Sun (elongation) to the east as an evening star and their greatest elongation west as a morning star.
The inferior planets (Mercury and Venus) go into retrograde only at inferior conjunction because this is when they are positioned between the Earth and the Sun. This alignment causes the apparent backward motion (retrograde) as the faster-moving Earth passes the slower-moving planet.
Mercury and Venus are the two planets that retrograde motion around the sun.
Venus and Uranus have retrograde rotation.There are other meanings of retrograde motion, but retrograde rotation fits the question best.
The observed retrograde motion of planets led Ptolemy to add epicycles to Aristotle's system. Epicycles were small circles that planets moved in on their larger circular orbits around Earth in order to explain the appearances of retrograde motion.
It doesn't. You may be thinking of Mars. Mars shows this effect because its distance and orbital speed are suitable.

Actually, 3 planets rotate in a retrograde motion, which, by the way, means that they rotate East to West, or in a counterclockwise motion. Most planets rotate in a clockwise direction, or West to East. The three planets that rotate in a retrograde motion are Venus, Uranus and Pluto.venus

The "apparent" reverse or backwards motion of a planet as observed from Earth. The innermost planets appear to have a retrograde motion when viewed from Earth.
Venus rotates by retrograde motion, which means it rotates in the opposite direction to most planets in our solar system. Its rotation period is longer than its orbital period, causing this unique motion.

Uranus and Venus are the two planets in our solar system that have a retrograde rotation. All of the planets orbit the Sun.
No, Ptolemy did.
Copernicus explained the retrograde motions of the planets by proposing that the Earth and the other planets revolve around the Sun in circular orbits. He suggested that the appearance of retrograde motion was a result of the varying speeds at which the planets orbited the Sun.
As of October 2021, the outer planets Uranus, Neptune, and Pluto are retrograde. Retrograde motion is an apparent backward motion of a planet as seen from Earth, and it can affect us by prompting introspection and reevaluation in the areas of life governed by the planet.
