Viewed from earth the moon appears to rock slowly backwards and forwards so that we see a slightly different face throughout the lunar month.

Our moon takes about 27 days to rotate around its own axis and 27 3 days to revolve around the earth. Click card to see definition.

There are two main reasons for this. First the moon s orbit around earth is elliptical not circular so its rotation is sometimes ahead and sometimes behind its orbital motion. This means that although the moon is rotating it always keeps one face toward us. How much of the moon is always lit up by the sun.
During this time it travels a distance of 1 423 000 miles 2 290 000 kilometers. This makes the same side always point toward us. One side of the moon tends to be pulled toward the earth more than the other. It occurs when one side of an astronomical body always faces another an effect known as synchronous rotation.

The moon spins exactly once for each time it goes around the earth. Tap card to see definition. Moon phase that occurs when the moon is between earth and the sun at which point the moon cannot be seen because its lighted half is facing the sun and its dark side faces earth. Known as synchronous rotation this is why we only ever see the moon s nearside from earth.
The simple answer is that we only see one side of the moon because the moon rotates around the earth at the exact same angular speed in fact it s not exactly true we ll talk about it later too as it rotates around its own axis so that the same side of the moon is constantly facing the surface of the earth. Why do we always see the same side of the moon the gravitational pull of earth on the moon causes the moon to move in an orbit around earth. Tap again to see term.
