How long does it take for the Moon to orbit the Earth?
A
31 days
B
30 days
C
29 days
D
28 days
Explanation: 

Detailed explanation-1: -The Moon takes about one month to orbit Earth (27.3 days to complete a revolution, but 29.5 days to change from New Moon to New Moon). As the Moon completes each 27.3-day orbit around Earth, both Earth and the Moon are moving around the Sun.

Detailed explanation-2: -The moon goes around the earth in every 28 days. Therefore we can see the shapes of the full moon, new moon and crescent moon in every 28 days.

Detailed explanation-3: -This is because it takes the same amount of time to spin on its axis once as it does to orbit the Earth once. The gravity between the Earth and the Moon caused this special case of tidal locking (called synchronous rotation).

Detailed explanation-4: -After all, it takes the moon around 28 days to complete its orbit around the Earth, moving through eight different phases of the lunar cycle. This cycle always begins with the new moon, reaches its peak during the full moon and then fades back into the night before starting the process all over again.

Detailed explanation-5: -The Moon takes 28 days to orbit Earth. As the Moon orbits the Earth, light from the Sun is reflected by the Moon’s surface. This allows us to see the Moon.

Detailed explanation-6: -Moon fact: The Moon’s phases repeat every 29.5 days, but it’s orbit around the Earth only takes 27. Why? In that time, as our Moon moves around Earth, the Earth also moves around the Sun. Our Moon must travel a little farther in its path to make up for the added distance and complete its phase cycle.

Detailed explanation-7: -The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still.
