The observed retrograde motion of planets led ptolemy to add blank to Aristotles system?
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.
What geometric arrangements did ptolemy use to explain retrograde motion?
Earths faster motion makes Mars appear to be going backwards, the backwards motion, in fact, is what caused retrograde motion. --Ptloemy used Epicycles to explain how geocentrical models worked.
Why does ptolemy include epicycles in his model?
Ptolemy included epicycles in his model to explain the retrograde motion of planets, where they appear to temporarily move backward in the sky. The epicycles were small circles that planets moved on while the center of the epicycle itself moved around Earth, providing a way to account for these complex observed movements within a geocentric system.
Which two planets have Retrograde motion?
Venus and Uranus have retrograde rotation.There are other meanings of retrograde motion, but retrograde rotation fits the question best.
What planetary phenomenon did Eudoxus solar system?
Retrograde Motion

Copernicus ideas that supported his ideas about the sun being at the centre of the Solar System?
he was a polish priest scientist stated retrograde motion occured whenever earth passes around another plant gained acceptance from people had a much simpliar way to explain retrograde motion than Ptolemy

What planetary phenomenon did Eudoxus solar system?
Retrograde Motion
The greek astronomers explanation for the celestial spheres did not encompass the phenomenon?
The Greek astronomer's explanation for the celestial spheres did not encompass the phenomenon of retrograde motion. The retrograde motion is the apparent motion of a planet to move in the opposite direction from the surrounding planetary bodies in the same system.
Why did Eudoxus create his solar system to explain what phenomenon?
retrograde motion
Why was retrograde motion important in astronomy?
Retrograde motion important in astronomy because it helped to explain that the planets revolved around the Sun. Retrograde motion is the ability of some objects to rotate in a direction that is opposite what is expected.
How did Nickolaus Copernicus account for the retrograde motion of the planets?
The retrograde motion of the planets is well modelled by both the Ptolemaic system and the Copernican system, and by the other models. But the Copernican system explains it more simply because, for example, Mars's retrograde motion is caused simply when Mars is overtaken by the Earth, which goes more quickly round the Sun. Thus an observer on the Earth sees Mars appearing to go 'backwards' on the ecliptic around the time of closest approach (opposition). This can be easily demonstrated by assuming simple circular orbits.
What is the planet that rotates by retrograde motion?
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
How do you use retrograde in a sentence?
retrograde is when a solar system object rotates clockwise while almost all other objects rotate counter-clockwise. "Venus' motion is retrograde in relation to the Earth's"
