Why do we only see one side of the moon?

Answer by  Anonymous

If you tie a string to a ball and then swing the ball around you, the same side of the ball always faces you. You are forcing the ball to make exactly one complete revolution about its own axis as each time it makes one revolution around you.

isnt it weird to think that the far side of the moon is never visible... only the apollo astronauts who have orbited the moon have seen it. it's sort of creepy to think about. what if they all have a secret and something strange is over there?

From Earth, we only see one side of the moon because the rotation of the moon on its axis is exactly the same amount of time as it takes it to revolve around the Earth -- 29.5 days. This is because, over time, the Earth's gravity has overcome the rotational force of the moon and locked it into step.

We only see one side of the moon because it rotates once per orbit around the Earth. This means that as it goes around the Earth, it rotates that same percentage of its face, resulting in the same face being visible at all times. This is called 'tidally locked'.
