Moon moves eastward?

Question

When it says that the moon moves eastward in its orbit from the new moon phase and forms a 90 degree angle with the sun and Earth, it's a first quarter, right?

Answer 1

Right.

Answer 2

That's correct.

However, the moon is actually moving westward. It appears in our sky to move eastward, from the west part of our sky to the east. But, the north pole of the moon points in a direction similar to our north pole. So, looking at the moon when it is at first quarter, at sunset, in the northern hemisphere, lunar north is up, lunar east is to the right, lunar south is toward the southern horizon, and lunar west is to the left. So, in moving eastward (right to left in our sky) it is moving toward it's own west.

Before NASA began sending probes to the moon the coordinates on the moon were related to directions in our sky, so the left limb of the moon was called east and the right west because that was the direction they pointed in the sky. But when lunar exploration started selenographers decided to use normal coordinate systems on the moon. So now, when lunar north is up, west is to the left, as it is on the earth.
