What Nationality is claudius Ptolemy?
Ptolemy was a Greek.
Describe what produces the retrograde motion of mars. what geometric arrangement did Ptolemy use to explain this 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.
How did Ptolemy account for the retrograde motion in his model of the Solar system?
Ptolemy used epicycles to explain the retrograde motions of planets.Each plant was assumed to move around a small circle that turns upon a large circle.
Did Galileo's observations confirm the validity of retrograde motion of the planets?
No, Ptolemy did.

The observed retrograde motion of planets led ptolemy to add blank to Aristotles system?
Epicycles
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
The apparent westward movement of a planet is known as?
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.
Why did Eudoxus create his solar system to explain what phenomenon?
retrograde motion
What were ptolemy's accomplishments?
Ptomleys accomplishments were his theory was that the Earth was the center of the universe. He also used to write about different things such as astronomy, geography, and logic.
Purpose of using epicycles and deferents to explain the motion of the planets in the night sky was to account?
retrograde motion
How did Copernicus explain the retrograde motions of the planets?
All the models explain retrograde motion because it is such an obvious phenomenon. In Copernicus's model an outer planet goes into retrograde motion when the inner planet overtakes it so that it appears from the inner planet to be going backwards along the ecliptic.
