Question

why do we see only one side of the moon​

Answer 1

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. ... For that reason, our moon always has one side facing Earth, which we call the moon's near side.

Answer 2

Answer:

one side of the moon around the earth takes about 27 days.

Explanation:

Because the moon's rotation about its own axis also takes nearly the same time one day of the moon is equal to 27 earth days. so only one side of the moon can be seen from the earth.
