The third celestial body featured in the Astronomy Garden is the Moon—the Earth's natural satellite. In addition to captivating the observer with its curiously cratered surface, the moon can also be used as a real clock.
People usually think that celestial objects can only be seen during the night, but there are times when we can see the Moon during the day. As it approaches its new moon phase, it rises in the morning and sets at the end of the day. When it is close to its full moon phase, the moon rises at sun down and sets at dawn.
