What is approximately the time it takes for the Moon to revolve around the Earth?

Moon. The real time for one orbit around the Earth is days, which is the true time for the Moon to orbit the Earth. However, since the earth itself is also orbiting the sun, the time when the moon circles and the earth and the sun at an angle is the sky, which is the synodic month, so the lunar calendar has 30 days of the big month and a small month.

29 days,

The rotation period is the same as the revolution period. This, of course, refers to using distant stars as references. When we take the earth as a reference, that is, in the eyes of human beings on the earth, then, genius is "a month", which is called the synodic month, that is, a cycle in which the moon is round and absent, and missing and round.

In this way, earthlings will also feel that the moon revolves around the sky. In fact, this is due to the difference between the heavens caused by the Earth's rotation around the Sun, because after a few days (say 27 days), the Earth is no longer in its original position, and the Moon has to travel a little longer to reflect the sun's light at the same angle, making the Moon appear to be the same as it was originally round. Therefore, earthlings generally refer to the "synodic month", that is, the day, as a month.

Scientifically, the true orbital and rotational periods of the Moon should be based on distant stars, i.e., heavens.

The moon revolves around the earth in one day, and the interval between the full moon and the full moon is the difference and relationship between the lunar calendar and the solar calendar: the solar calendar is also the Gregorian calendar, which is internationally applicable. The solar calendar is based on the time it takes for the earth to make one revolution around the sun, with a total of 365 days, 5 hours, 48 minutes and 46 seconds.

In ordinary years, only the whole number of 365 days is counted, and the mantissa is not counted; The year is divided into 12 months, with 31 days in the big month, 30 days in the small month, and only 28 days in February.

The globe is the only natural satellite of the Earth. It takes 8 minutes for sunlight to reach the Earth, and the average distance is 15000000 kilometers. The average distance from the Moon to the Earth is only 384404 kilometers, which is about 60 times the radius of the Earth. The time it takes for the Earth to revolve around the Sun is one year, while the time it takes for the Moon to revolve around the Earth is equal to the number of days on Earth. The rotation time of the Earth on its axis from west to east is 23 hours and 56 minutes, which is one day and night of the Earth; However, the period of rotation of the Moon is exactly equal to the period of one rotation of the Moon, so one day of the Moon is equivalent to one of the Earth.

The time it takes for the Moon to orbit the Earth is a day, which is called a sidereal month, which is the true cycle of the Moon's revolution, that is, the time between the Moon's two passes through the Earth and a star.

However, the Moon not only orbits the Earth, but also accompanies the Earth around the Sun, from this Full Moon to the next Full Moon or by this New Moon.

Until the next new moon, the cycle is days, which is called a synodic month.

This cycle is a bit longer than the sidereal month.

Brief introduction. The length of the solar year in the Hijri calendar is 354 days, but there is a difference of 8 hours, 48 minutes and 36 seconds from the actual length of the 12 synodic months. Therefore, in order to solve this problem, the Hijri calendar arranges 11 leap years of 355 days in the 30 lunar years, and divides December of the leap year into small months.

Changed to Otsuki. The lunar month of the Hijri calendar is roughly the same as the old Chinese calendar. However, in the old calendar of our country, the first day of each month is determined by the conjunction of the sun and the moon, and the first day of the month is determined by the beginning of the month in the Hijri calendar, and this phenomenon appears on the second or third day of the first month of the old calendar in our country.

Therefore, the first day of the Hijri calendar is equivalent to the second or third day of the old calendar in China.

The real time of the moon orbiting the earth is days, which is the real time of the moon orbiting the earth, but because the earth itself is also orbiting the sun, the time when the moon orbits the earth and the sun at an angle is the day, which is the synodic month, so the lunar calendar is 30 days in the big month and 29 days in the small month, so the lunar calendar in China is formulated with reference to the operation of the moon.

The moon revolves around the earth once in the sky. The cycle of the moon around the earth is also known as the "sidereal month", in addition to orbiting the earth, the moon itself is still rotating, the cycle of the moon's rotation is 27 days, 7 hours, 43 minutes and seconds, which is almost equal to the period of its revolution around the earth. The Moon is the Earth's natural satellite and one of the first planets to be discovered.

Dear, I hope my answer is helpful to you!

How much does the moon make one revolution around the earth.

The true time of the Moon's orbit around the Earth is days.

The moon revolves around the earth once called a "month". The duration of the month is divided into sidereal and synodic months.

A sidereal month is the rotation period of the Moon for a star. If a point on the moon that was originally facing the sun returns to its original position after a period of time, this cycle is called a sidereal moon. The sidereal moon is the true orbital cycle of the Moon.

A sidereal month is the day, or 27 days, 7 hours, 43 minutes and seconds.

A synodic month is the average period of the Moon's revolution around the Earth relative to the Sun. This is the average period of the moon phase. That is, the cycle of the waxing and waning of the moon is called a "synodic month". A synodic month averages days, or 29 days, 12 hours, 44 minutes, and 3 seconds.

Sidereal Month in relation to synodic months.

In the diagram above, the Moon starts at position A, orbits the Earth once and at position A, it completes one revolution and becomes a sidereal month. The sidereal moon is the true orbital cycle of the Moon.

When the Moon completes a sidereal month, looking at the Moon from Earth, the Moon has not yet completed a synodic cycle, has not completed a synodic month. The Moon has to continue to rotate a little more in its orbit and return to the middle position c of the Sun-Earth line again to complete a synodic moon.

So the synodic month is about 2 days longer than the sidereal month.

We usually use synodic months, not sidereal months. The sidereal moon has nothing to do with our daily lives.

It is a month for the Moon to revolve around the Earth. One month of constant rotation and reversal.

One month, the actual number of days.

It takes about a few days for the Moon to orbit the Earth. This number is also known as the moon's "orbital cycle" or "moon cycle". However, the Moon's orbit is elliptical, so there will actually be slight variations in the amount of time it takes to orbit the Earth.

Sometimes the Moon's orbital period is slightly longer than the days, and sometimes it is slightly shorter.

Moon.

29 days 12:44:3 seconds. The Moon revolves around the Earth and is a synodic month.

It is 29 days, 12:44:3 seconds, and the Earth orbits the Sun for about 365 days. There is such a relationship between the years, months, and days.

The Earth and the Moon rotate together around the Earth-Moon center – this center is in the interior of the Earth, so it looks like we think the Moon revolves around the Earth.

Target. The direction of the revolution is from west to east – that is, the Moon rotates counterclockwise around the Earth from the north pole of the Earth, and the Moon rotates clockwise from the south pole of the Earth.

Orbiting the Earth. The revolution period is a little over 29 days.

The Moon rotates in a direction from west to east. That is, the rotation and revolution of the moon are the same. The rotation period is also a little more than 29 days, so the moon always rotates on one side towards the earth.

About the moon's self-**

The Moon rotates while revolving around the Earth, and the period day is exactly a sidereal month, so we can't see the back side of the moon oak that happens to be the ball.

This phenomenon is called synchronous rotation, and it is almost a universal law in the satellite world. It is thought to be the result of the long-term tidal action of the planets on the satellites. The balance movement is a wonderful phenomenon that allows us to see 59% of the surface of the moon. There are several main reasons:

1) In different parts of the elliptical orbit, the rotation speed is the same as the angular velocity of the revolution.

Mismatch. 2) The intersection of the white and equator.

The Moon revolves around the Earth.

There are two cycles, one is a synodic month and the other is a sidereal month.

The synodic month is the average cycle of the moon's phases. That is, the time interval from the new year to the next new day or from the hope to the next time the potato rises, the average is days. That is, from the earth, the moon is full and waning. The synodic month is not a true orbital cycle of the Moon.

A sidereal month is the orbital period of the Moon relative to a star, and a sidereal month has days, or 27 days, 7 hours, and 43 minutes and seconds. The sidereal moon is the true orbital cycle of the Moon.

The period of the Moon's revolution around the Earth is the Heavens, also known as the sidereal months.

It takes one month for the Moon to revolve around the Earth.

It's also a lap. The rotation period of the Lunar Split Friendly is the same as the rotation period, and the Moon makes one rotation from the source of the sail at the same time as the first circle.

The exact time of the Moon's rotation and revolution is days (709 hours).

It's about twenty-eight days, which we call the lunar calendar, or the lunar calendar
