The observed retrograde motion of planets led ptolemy to add blank to Aristotles system?
Epicycles
What planetary phenomenon did Eudoxus solar system?
Retrograde Motion
Why did Eudoxus create his solar system to explain what phenomenon?
retrograde motion
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.
Which planet rotate in retrograde motion?
Uranus and Venus are the two planets in our solar system that have a retrograde rotation. All of the planets orbit the Sun.

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

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"
What is the name given to the phenomenon in which the apparent motion of the planets sometimes reverses?
Retrograde motion happens when the Earth overtakes an outer planet in its orbit. It happens around the date of Opposition when the planet is opposite the Sun in the sky. Usually planets travel from west to east along the ecliptic, but during retrograde motion they travel backwards, from east to west,.
Which planet rotate in retrograde motion?
Uranus and Venus are the two planets in our solar system that have a retrograde rotation. All of the planets orbit the Sun.
When a planet spins in the opposite direction of the other planets in a solar system what is it called?
A retrograde motion.
When a planet spins in the opposite direction of the other planets in a solar system it is called what?
A retrograde motion.
When a planet spins in the opposite direction of the other planets in a solar system it is called .?
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.
