Explain how Copernicus concluded that stars were farther away than planets?

Copernicus decided this with more of an educated guess than anything. For example is when your standing right next to a plane it's huge Right? Well when it's flying it looks really small. He used the same reasoning for stars. Since it looks small it must be farther away.

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.
Who was The scientist who asserted that the planets move around the sun in a circular orbit?
Isaac Newton
Who invented the movement of planets around the sun?
Nicolaus Copernicus
How was Copernicus' model of the universe different from Ptolemy's model?
The main difference was that Ptolemy's model was geocentric (Earth-centred) and Copernicus's was heliocentric (Sun-centred). Ptolemy's model came from ancient times while Copernicus's was much later (1543). Both models represented the planets' orbits by using combinations of circles and epicycles to explain the way the planets move among the stars. Copernicus found that the orbits of the inner planets could be explained more simply. That is to say that the epicycles used for all the orbits were smaller, and for the inner planets a lot smaller. Both models represented the planets' positions with reasonable accuracy given the crude observational methods used in those days. Until gravity and the laws of dynamics were discovered about 150 years after the publication of Copernicus's system, there was no way of deciding which model was the 'right' one.
Who proved the accuracy of Copernicus ideas about motion of planets?
Johannes kelper
Why did Copernicus think that stars are farther from earth than the planets are?
He knew that the planets revolved around the sun in an elliptical orbit.
