Like planets, the moon does not emit its own right. The Moon is ~1/4 of the Earth in diameter and ~1 percent in mass. The rotation of the Moon and its revolution around the Earth are synchronized and take 27 days,7 hours, and 43 minutes. The length of the Lunar orbit around Earth ( Sidereal Period ) is 27.32 days. The length of the Lunar Phase ( Synodic Period ) is 29.53 days. We only see one side of the moon.
