Moon Rotation Period Explained
The time it takes for the moon to complete one full rotation on its axis is known as its rotation period.
Synchronous Rotation of the Moon
The moon exhibits synchronous rotation, meaning its rotation period is the same as its orbital period around the Earth. This is why we always see the same face of the moon from Earth.
Rotation Duration
The moon takes approximately 27.3 earth days to complete a single rotation on its axis relative to the stars (sidereal rotation period).
This duration is also very close to its orbital period around the Earth.
