Count the days and calculate them
In that case, the Moon would have to be much closer to Earth (you can calculate the distance using Kepler's Third Law); the tides would be much stronger.
It takes about 3 days to get to the Moon from the earth.
It takes precisely 27.3 Days for the moon to orbit the earth.
It takes about 28 days for the moon to orbit the earth.
It takes 27.3 days for the moon to orbit the Earth

27 1/3 days to orbit the earth however the number of days between a full moon and the next full moon is 29 1/2 days.
In that case, the Moon would have to be much closer to Earth (you can calculate the distance using Kepler's Third Law); the tides would be much stronger.
It takes the moon 29 days or about 1 month to orbit the earth.
Days on the moon are 29.531 earth days long.
Mainly, to revolve around the Earth in 15 days, the Moon would have to be closer (you can calculate the ratio using Kepler's Third Law). This would make the tides stronger.
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.
It takes the Moon about 27.3 Earth days to orbit around the Earth.
It takes about 3 days to get to the Moon from the earth.
Days on the Earth are 24 hours long. Days on the Moon are about 29.5 days, or 709 hours.
It takes precisely 27.3 Days for the moon to orbit the earth.
