Final answer:
The Moon takes approximately 30 days to orbit once around the Earth.
Step-by-step explanation:
The Moon takes approximately 30 days to orbit once around the Earth. This period is known as the lunar month or the synodic period.
While the Moon's orbital period measured by the stars is about 27.3 days, the monthly cycle of the Moon, from new moon to new moon, takes around 29.5 days due to the changing position of the Sun in the sky.
