Moon Movement: Rotation and Revolution
–
–
The rotation of the moon is the rotation of the moon on its axis. For one rotation, the moon takes 29.5 days or 1 month. The period of the moon’s rotation is the same as the period of the moon’s revolution around the earth. As a result of the moon’s rotation, the surface of the moon looks the same from Earth.

The result of the moon’s revolution is the occurrence of high and low tides. The full tide occurs when the full moon and new moon, while the new tide occurs during the half moon.
—
In addition to the motion of the moon’s revolution around the earth, the moon also revolves around the sun. The time of revolution of the moon around the sun is the same as the time of revolution of the earth. So in 1 year, the moon moves 1 time around the sun and 12 times around the earth. This is why there are 12 months in 1 year in the Gregorian calendar.

The phase of the moon or the phase of change of shape (position) of the moon includes the new moon, half moon, full moon, half moon. For a month, each phase takes 7.5 days. Such is the brief explanation of the movement of the moon: rotation and revolution of the moon. I hope this information is helpful! (CHL)
