It's always the same moon, but the shape of the visible lighted portion changes.
Whatever shape of the moon you see right now, you'll see the same shape again
after 29.53 days have passed.
It takes about 29.5 days for the moon to complete a full lunar cycle and reappear in the same phase. This cycle includes all the phases of the moon, from new moon to full moon and back to new moon again.
Whatever moon phase you're looking at, it was the same 29.53 days ago, and it'll be the same again after another 29.53 days.
A "Moon year" is almost exactly the same as an Earth year. That's about 365 Earth days. The Earth and Moon orbit the Sun in about 365.25 Earth days. So the answer is: about 365. If you mean how many "Moon days" in one Moon year, that's different. The Moon rotates in about 27.3 Earth days. That's one definition of a "Moon day". In that case the answer is about 365/27.3 days = about 13.37 days.
The full cycle of the moon's phases, from the occurrence of any one of them until the next occurence of the same one, runs 29.53 days.
It takes 27.3 days for the Moon to revolve around the Earth, and the same amount of time to rotate on its axis.
It takes about 29.5 days for the moon to complete one full cycle of phases and return to its starting position. This period is known as a lunar month.
The moon takes about 27.3 days to spin around its axis once, which is the same amount of time it takes to complete one orbit around Earth. This synchronous rotation is why we always see the same face of the moon from Earth.
They are in the same orbit
The moon rotates on its axis once each 27.32 days. Also, the time it takes to complete one orbital revolution around the Earth is exactly the same as its rotation period. That's why the "face" of the moon visible from Earth is always the same.
A year on the moon is approximately the same as a year on Earth, about 365.24 days.
The moon does not circle the sun directly, it circles the earth. so it would be approximately the same as how long the earth takes, about 365 days.
As the Moon revolves around the Earth, the time taken to revolve around the Sun is the same as the Earth ~365.25 days or one year.
