Just like Earth, our Moon rotates on its own axis and experiences day and night cycles. Our Moon's day is longer than Earth's — the Moon spins on its axis once every 27.3 days. The Moon takes the same amount of time to spin around once as it does to orbit completely around Earth. This means that Earth observers always see the same side of the Moon (called the "nearside"). The side we do not see from Earth, called the "farside," has been mapped during lunar missions.
