Summary
The moon revolves around Earth, while the Earth-moon system orbits the sun. Both Earth and the moon rotate on axes and have day-night cycles. As Earth, the moon, and the sun travel through space, they sometimes line up to produce eclipses. Many of the features on Earth and the moon are different, although some landforms occur on both.
