Apparent retrograde motion occurs when a planet appears to move in which direction relative to the background stars?

Explanation:
Apparent retrograde motion is an illusion created by watching planets from Earth as we both orbit the Sun. Planets normally drift eastward against the background stars, but when Earth, on a faster inner orbit, catches up to and passes a planet, that planet appears to slow, stop, and then move westward relative to the distant stars for a while before resuming its usual eastward motion. This westward swing is the retrograde phase.
