The Earth's Moon is "tidally locked" to Earth, meaning that it rotates (spins) exactly once each time it orbits the Earth. This means that we always see the same face of the Moon.

The length of the Moon's rotation (and orbit) is 27.3 days but because the Earth-Moon system orbits the Sun, it is about 29.5 days between full moons, and this period (29 or 30 days) is referred to as the "lunar month."

EAST-WEST LIBRATION The moon's libration is an apparent motion of the moon, and not a true motion. It is the apparent slight swinging back and forth of the moon once during each lunar cycle (a complete series of moon phases). It is not observable directly with the naked eye because the cycle is so long and the movement is not extreme. If you use good astronomy software, you can easily observe this libration. You might have success observing it by taking excellent photographs of the moon each night for a month. Here is what is happening. The moon rotates on its axis once during each lunar cycle, and this is because the moon is tidally locked with the earth. This is an entirely separate topic for those who want to know more. The moon also orbits the earth once during each lunar cycle (the synodic period). The moon's orbit around the earth is not perfectly circular; it is elliptical as are almost all orbits in the solar system. This means that the moon is closest to the earth (perigee) at one point during the lunar cycle, and farthest away roughly 2 weeks later. When the moon is approaching perigee, it speeds up a little in its orbit, reaching a maximum velocity right at perigee. It then begins to slow down reaching its slowest orbital velocity at apogee, about 2 weeks later. But the rotational velocity of the moon is virtually constant throughout the month. If you think about this, the moon will be moving around the earth faster at the time of perigee, but because the rotational velocity of the moon isn't changing, the moon will appear to be swinging its face a little toward the east (a little more of the moon's west surface will show). The rotation will appear to us to be out of synch with the orbit. This appears to be true not because the moon is really swinging, but because of the difference between orbital and rotational velocities. At the other side, the moon's orbit is slowing slightly while the rotational velocity remains the same. So the rotation again appears to be out of synch with the orbit. The result of all this is the apparent swinging of the moon. NORTH-SOUTH LIBRATION There is also a north-south libration that comes about because the moon does not orbit the earth in the earth's or the moon's equatorial plane. As a result of this, we can 'peak' over the top of the moon at times during its orbit, and at other times we can 'peak' underneath. This too is an apparent and not a true motion of the moon.

When the moon appears at its highest altitude in your sky, it's due south of you

if you're located in the northern hemisphere, and due north of you if you're located

in the Southern Hemisphere.

The Moon orbits the Earth in a counter-clockwise direction if looking down on the Earth. The Moon itself is tidally locked with the Earth, which means that the Moon rotates on its own axis at the same rate as it rotates around the Earth thus showing only one face towards us at all times. This direction is also counter-clockwise.

The rotation of the moon is the moon spinning in one place.

The moon rotates and revolves, just like the Earth, and thus does not really face any one thing. It is constantly turning.

It rotates in such a way that it basically always shows Earth the same side. That means that in one of its revolutions around the Earth (about 27 1/3 days), it rotates once.

What direction is the moon facing for tonight?

The direction the moon faces changes throughout the night as it moves across the sky. You can determine the moon's current direction by using a compass or a stargazing app that shows its location in real time.


IS the moon facing west or east when it is a full moon?

The Moon has no east-west direction with respect to Earth. East-west describes the direction of, or opposite direction of a sphere that is rotating. (Like Earth.) As it turns out, the same side of the Moon always faces the Earth. The phases of the Moon, like full Moon, result from which direction the SUN is from the Moon and Earth.


How will you describe the moon when it is in the general direction of the sun?

When the moon is in the general direction of the sun, it appears as a thin crescent or a new moon, with only a small portion of its illuminated side visible from Earth. This is because the sun is illuminating the side of the moon that is not facing us.


When the unlighted side of the moon faces earth you have a new moon?

Not quite! A new moon occurs when the side of the moon facing Earth is not illuminated by the sun, making it appear dark. This happens when the moon is positioned between Earth and the sun.


Where is the moon when it is full?

At full moon, the Moon is opposite the Sun. It will (approximately) rise at sunset, and set at sunrise.At new moon, the moon is in the same direction as the Sun. It is still there, we just cant see the side lit by sunlight as it is facing away from the Earth when in the New Moon phase.


How would the side of the moon that faces us have craters at all if it is facing us here on earth?

Space rocks can come from any direction; they can miss the Earth and then whack the Moon's nearside.


How does the moon affect the tides on the side of earth facing the moon?

There are high tides on the side of Earth facing the moon.


If you are facing north what direction is behind you?

If you are facing north, the direction behind you would be south.


How does the moon position affect the tides of earths ocean?

Wherever the moon is, the mass of water on Earth facing AND opposite of the Moon are pulled outwards because of the Moon's gravity. The mass of water facing the Moon is pulled out because its gravity is stronger there. Thhe mass of water facing AWAY from the moon is pulled out because of the LACK of moon gravity on it, if that makes sense. Wherever is not facing the moon or directly away from the moon has low tides because the moon's gravity does not much affect that area and the water from there rushes to the areas facing and facing away from the moon.
