Answer

Brief Explanations:

In Copernicus' heliocentric model, retrograde motion of a planet occurs when Earth, which moves faster in its orbit around the Sun, passes a slower - moving outer planet. The relative motion makes the outer planet appear to move backward in the sky from our perspective on Earth.

Answer:

Earth passes the planet while they orbit.
