Answer 2

Answer:

One side of the moon always faces Earth because of what’s called synchronous rotation. That is, the moon rotates, or spins on its axis, in the same length of time it takes to orbit Earth. Any moon whose rotational period equals its orbital period is said to exhibit synchronous rotation, a characteristic shared by many moons of our solar system. Because of synchronous rotation or tidal locking, our moon rotates on its axis in the same period that it revolves around the Earth: 27.32 days. For that reason, our moon always has one side facing Earth, which we call the moon’s near side. Meanwhile, the opposite side remains hidden from us, so we refer to it as the moon’s far side.
