Does the Moon spin while it orbits the Earth? Yes, the Moon revolves around the Earth, completing one full orbit every 27.3 days. Because the Earth is also moving around the Sun at the same time, it takes about 29.5 days to complete the full cycle of lunar phases. [1, 2, 3] The Moon also rotates on its own axis, completing one full spin in exactly the same amount of time it takes to orbit the Earth. This perfect synchronization, known as "tidal locking," means the exact same side of the Moon perpetually faces Earth. [1, 2, 3]
