Question

Quizplus · Accepted Answer

Retrograde motion is the apparent backward motion of a planet or celestial object as seen from Earth. The Moon does not experience retrograde motion because it orbits around the Earth in the same direction that the Earth rotates, so it always appears to move in the same direction in the sky. Mercury, Mars, and Jupiter all exhibit retrograde motion at certain times because of their positions relative to the Earth's orbit.
