They are in the same orbit
On the average, 365.23 days, same as the earth. If it were not the same as the earth, thenover a period of just a few years, the moon would recede noticeably from the earth, either outahead of us or falling behind us.
It take 27.32 days for the moon to revolve around the earth. At the same time, the Earth and moon revolve as a bound pair around the sun every 365.25 days.
It isn't. A "day on the Moon" is about 29.5 Earth days; a year is about 365 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.
A year on the moon is approximately the same as a year on Earth, about 365.24 days.
A day on the moon is 29.5 Earth days. The moon takes 27.3 days to fully orbit the Earth. This is called a sidereal day.
The length of daylight on the moon is about 14 Earth days, followed by 14 days of darkness. This is because the moon takes the same amount of time to rotate on its axis as it does to orbit the Earth.
If a "day" is the time from one sunrise to the next, then on the moon, that's roughly 29 earth days.
The rotation of the moon on its axis, and the revolution of the moon in its orbitaround the earth, both have the same identical period: 27.32 days (rounded)
A day on the Moon (about 29.5 Earth days) is the same length as a year on Earth (365.25 days) because of a phenomenon called synchronous rotation. The Moon's rotation period is the same as its orbit around Earth, causing one side of the Moon to always face Earth, leading to equal lengths of day and year.
The moon keeps one side facing the Earth as it revolves around Earth. This means that for every revolution, there is exactly one rotation. The moon takes about 29.53 days to revolve around the Earth (This is the synodic period: consider the time to go from one 'new moon' to the next. The synodic period brings the moon all the way back to the same position relative to the sun). But the moon's true (sidereal) rotational period is about 27.32 days, because we have to take into consideration that the moon is rotating and orbiting at the same time.
The Moon actually orbits the Earth, which it does in 28 days, but if you consider the Earth and the Moon as a double system, then the Moon orbits the Sun once a year, just as the Earth does. The Moon is much closer to the Earth than the Earth and the Moon are to the Sun.
