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.

Why was it difficult for ancient astronomers to explain about the apparent retrograde motion?
If, as ancient astronomers thought, that our Earth was the center point of rotation for other planets, then it is difficult to explain why those planets would move in a direction opposite to their rotation. Ptolemy came up with a solution that worked, but it was a cumbersome one. Nicolae Copernicus was able to show that this retrograde motion could be explained easily if it were assumed that our Sun was the actual center of rotation of the planets.
Which planets have retrograde?
If you mean "retrograde rotation", they are Venus and Uranus.
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.
What two planets that retrograde motion around the sun?
Mercury and Venus are the two planets that retrograde motion around the sun.
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.
Whast were the spheres of Eudoxus?
A mathematical representation of the orbits of the planets, configured in a way that planets would have figure eight motions that would partially explain retrograde motions.

Purpose of using epicycles and deferents to explain the motion of the planets in the night sky was to account?
retrograde motion
Who used 80 wheels within wheels to explain the retrograde motion of the 5 visible planets?
KEPLER
Major advantage of Copernicus' Sun-centered model over the Ptolemaic model?
It offered more natural explanation for the apparent retrograde motion of planets in our sky.
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.
Which planets have retrograde?
If you mean "retrograde rotation", they are Venus and Uranus.
Which planets orbit in a retrograde rotation?
The planets Venus, Uranus and Pluto rotate in retrograde rotation. Hope that helped ~ :-))
What planet has a retrograde revolution?
Retrograde refers to a planetary movement in which specific planets turn in a different direction than others. Planets with retrograde movements are Uranus and Venus.
What two planets that retrograde motion around the sun?
Mercury and Venus are the two planets that retrograde motion around the sun.
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.
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.
