What are the different mysteries of the moon?

Answer 1

There are many interesting facts about the moon, perhaps not mysteries though. For example, one may find it interesting that the same side of the moon always faces earth. In other words, without the help of satellites, we would have never even seen what the "dark" side of the moon looks like. The dark side of the moon is not actually even dark all the time. It only seems that way to us because we never see it. Sunlight hits the back side of the moon just as often as it hits the side that we see. The reason that we never see that side of the moon is because the moon is in a gravitational lock with the earth. Its orbit is equal to the rotation to the earth. So one earthly rotation (1 day) is the same amount of time that the moon takes to travel around the earth (one lunar year).
