Why Do We See The Same Side Of The Moon From Earth
Olivia Luz
Simply said because the moon s rotation coincide with its orbit around the earth we only see the same surface of the moon.
There are two main reasons for this. As a result the same lunar hemisphere always faces earth. The moon is directly illuminated by the sun and the cyclically varying viewing conditions cause the lunar phases. From earth we always see nearly the same face of the moon.
The whole earth sees the same moon phase on the same day but the northern and southern hemispheres see the moon oriented differently with respect to the horizon. A simple demonstration shows the idea. Well this is due to the fact that the moon s orbit is elliptical and not circular. Our lunar companion rotates while it orbits earth.
The near side of the moon is the lunar hemisphere that is permanently turned towards earth as opposed to the opposite far side only one side of the moon is visible from earth because the moon rotates on its axis at the same rate that the moon orbits the earth a situation known as synchronous rotation or tidal locking. But why 59 percent and not 50 percent. This happens because the moon rotates on its axis in the same amount of time it takes to orbit earth a trait called synchronous rotation. Only one side of the moon is visible from earth because the moon rotateson its axis at the same rate that themoon orbits the earth a situation known as synchronous rotation or tidal locking.

As the moon orbits the earth the same side is facing the earth but the shadow moves across the whole of the moon. There s no such thing as a permanently dark side of the moon. And second the moon s rotation axis is not at right angles to its orbit around the earth so we can sometimes see over or under its poles. It s just that the amount of time it takes the moon to complete a revolution on its axis is the same it takes to circle our planet about 27 days.
The moon is directly illuminated by the sun and the cyclically.
