Question

Quizplus · Accepted Answer

Planets appear to move west to east relative to the background stars due to their orbital motion around the Sun. This is known as prograde motion. However, due to the relative motion between Earth and the planets, they may appear to briefly move east to west (known as retrograde motion) before continuing on their prograde path.
