How many days is a day on the Moon equivalent to the Earth?

Some people think that what we see on Earth is always only one side of the moon, and it should not rotate, but it is notThe Moon also has a rotation period, but the Moon is also greatly affected by tidal gravity and does not have an atmosphere, and the rise and fall between the two planets are different.

Since the rotation speed of the moon is slower than that of the earth, it seems that the beginning of the year on earth is just one day in the sky, and scientific studies have shown that the moon rotates for 180 hours is only equivalent to the earth's day, and another 180 hours is only the earth's night generalSo one day of the moon is equal to one month of the earth, although the data is not as exaggerated as rumored.

Scientists have found that the time for the moon to make one revolution is about one month, which means that its rotation is also one month. Doing the math we will find that a day on the Moon is equivalent to a year on Earth. Although this is a bit different from the legendary saying "one day in the sky, one year underground", it is a long time period.

Astronomers have determined that the exact period of the Moon's revolution is days, so a day on the Moon is equivalent to an hour on Earth. Throughout the universe, the moon is not the only one with such a peculiar phenomenon, almost all planetary systems have such a law. Because some of the closest moons are locked by the planet's gravity, the orbital period and the rotation period are the same.

So in the future, if humans are going to live on the moon, they have to be prepared to adapt to such a long day.

While the Moon orbits the Earth, it is also constantly rotating from west to east. Therefore, there is also the phenomenon of the sun rising in the east and setting in the west on the moon. However, this is completely different from the "sunrise" and "sunset" that we see on Earth.

After the sun rises in the east from the moon, it takes more than 180 hours to rise to the middle of the sky; It will take more than 180 hours to move from the midsky to the western "horizon"; After more than 360 hours of darkness, it can be counted as a "day and night".

When the sun comes out, the sun seen "during the day" is a thousand times brighter than the sun seen on Earth, because there is no atmosphere around the moon. The temperature on the surface of the moon can reach 127, and even in the "daytime", you can still clearly see the stars in the dark sky and the mutilated earth due to the change of "earth's appearance"!

As soon as the sun goes down, night covers the moon – and the long night begins! The "night" lasted for about two weeks, and the temperature dropped to minus 183 degrees Celsius. In the dark night sky, you can see a huge "bright moon" - the earth that reflects the sunlight hangs high in the sky, "shining brightly", and the brightness is 80 times brighter than the moon we see on the earth!

The Moon is an ideal place to set up an observatory because there is no interference from the atmosphere and dust, and the stars can be clearly observed day and night, which is much more advantageous than on Earth.

In fact, each planet will have its own rotation orbit, and the definition of time is different, such as the time for our earth to rotate once is one dayAnd the time to revolve around the sun is a yearBut the rotation of the moon is much longer than that of the earth, I wonder what you think about it? Scientists say that the equivalent of a month on Earth is a little unexpected.

As early as the 60s of the last century, the Americans have set foot on the moon, it can be seen that the moon is very attractive to the United States and our China and many countries in the world, human beings in addition to hoping to establish a base on the moon, but also hope to make good use of some precious resources on the moon can be used by human beings, that is the so-called knowing oneself and knowing the other, in order to win all battles, we all know that the moon is a very small gravitational request, astronauts must wear very heavy spacesuits, Dare to walk on the surface of the moon, otherwise it is likely to jump to the height of several floors with a slight jump, and at the same time, there is no air on the moon, let alone the existence of oxygen, so it seems that the dream of human beings to settle on the moon is almost unrealizable! <>

However, this does not prevent human beings from continuing to be interested in the moon, to say a more interesting topic, in mythological stories, there is often such a sentence called one day in the sky, one year underground, then the moon is also high in the sky for most of us, if human beings really travel to the moon in the future, sleep on the moon for a day, equivalent to how long on the earth to spend? Scientists have the answerBut it was a very surprising answer!

One day in heaven, one year on earth? The answer is unexpected, since ancient times, Chinese have this complex of moon exploration, the reason is because ancient mythology depicts a very beautiful mythical image on the moon, that is, Chang'e, then in modern times, Chinese have been rushing to the process of landing on the moon, and at the end of last year, China sent Chang'e 4 to the back of the moon for the first time, and it was also the first time that all mankind saw a complete image of the moon, At present, Chang'e-4 and Yutu-2 are still working step by step on the far side of the moon!

Since ancient times, there has been a saying that there is a day in the sky and a year on the earth, which describes the difference between immortals and mortals, so what about the time of a day on the moon is equivalent to a few days on the earth? Then the following is byKnowledge of horoscopesOur human exploration of the universe began from the earth, in the long-term exploration, we know that the rotation of the earth is 24 hours, that is, a day, but the ancients are different from us, they do not know what the earth is, let alone the world outside the earth, they do not have our current scientific theoretical knowledge, but the time between the body and the body is different, on our earth, a day needs 24 hours, so what is the time on the moon?

The rotation mode of the moon is actually very different from that of our earth, because of the existence of tidal force, the earth basically controls the moon, because the moon has been firmly controlled by us, so for human beings on our earth, because of the existence of this tidal force, it is equivalent to an invisible bond between our earth and the moon.

There are many people who say that there is no rotation period on the moon, which is actually wrong, and the moon also needs to rotate like our earth, but the length of time is slightly different from our earth.

According to scientists' calculations, it takes 23:56 for the Earth to complete its rotation every time, which is what we call a day, and the period for the Moon to complete its rotation is a day, so it seems that there is a one-month time gap between the two planets.

That is to say, according to the inference of scientists, if we stay on the moon for a day, it is equivalent to a month on the earth, and this also breaks the conclusion that the ancients have always believed that one day in the sky and one year on the earth, but if one day is a month, such a time is still very long.

A day refers to the time when the sun rises to set and then rises, and the day that the Moon undergoes this process is equivalent to one month on Earth. We see that the moon keeps rising and falling mainly because of the rotation of the earth, the moon is tidally locked by the earth, so only a circle around the earth is considered a day, on the earth exactly after a month, the lunar month is actually the best time record reflecting the movement of the moon.

Because the rotation speed of the moon is slower than that of the earth, it seems that the beginning of the year on the earth is just a day in the sky, scientific studies have shown that the moon rotates for 180 hours is only equivalent to the earth's day, and another 180 hours is only the earth's night general, so the moon is equal to the earth for a month, although the data is not as exaggerated as rumored.

Phenomenon. However, this is completely different from the "sunrise" and "sunset" that we see on Earth.

After the sun rises from the east on the moon, it takes more than 180 hours to rise to the middle of the sky, and it takes more than 180 hours to move from the middle heaven to the west "horizon" and set, and then more than 360 hours of darkness before it is a "day and night". To be exact, a day and night on Earth is 23 hours, 56 minutes and 04 seconds, and a "day and night" on the Moon is as long as a day.

As early as the 60s of the last century, the Americans have set foot on the moon, which shows that the moon is extremely attractive to the United States, China and many countries in the world.

We all know that the moon is a very small gravitational request, astronauts must wear very heavy spacesuits, dare to walk on the surface of the moon, or it is likely to jump a few floors of height with a slight jump, and at the same time there is no air on the moon, and there is no oxygen, so it seems that the dream of human beings to settle on the moon is almost unrealizable!

Hello, I'm glad to provide you with an answer, a day on the Moon is equivalent to 655 hours on Earth, which is a day. The rotation period of the Moon is equal to the revolution period and is days, while each day on Earth is 24 hours. So a day on the Moon is equivalent to a day on Earth. 

While the Moon revolves around the Earth, it is also constantly rotating from west to east. Therefore, there is also the phenomenon of the sun rising in the east and setting in the west on the moon. However, this is completely different from the "sunrise" and "sunset" that we see on Earth.

On the Moon, it takes more than 180 hours for the sun to rise from the east to the middle of the sky; It takes more than 180 hours to move from midheaven to the western "horizon"; After more than 360 hours of darkness, it can be regarded as a "day and night".

One day on the Moon is equivalent to one day on Earth.

The Moon rotates while revolving around the Earth, and the period day is exactly a sidereal month, so we can't see the far side of the Moon. This phenomenon is called "synchronous rotation", or "tide locking".

The Moon moves half a degree per hour relative to the background starry sky, i.e. it is similar to the apparent diameter of the Moon's surface. Unlike other satellites, the Moon's orbital plane is closer to the ecliptic plane than near the Earth's equatorial plane. The time it takes for the Moon to orbit the Earth (one sidereal month) is called a sidereal month, relative to the background starry sky; Whereas the time it takes for a new moon to take for the next new moon (or between two phases of the same moon) is called a synodic month.

Moon. A day and night on Earth is equivalent to a month on Earth (a synodic month.

about days). Then one day on the moon is equivalent to about half a month on Earth.

The Moon is a satellite of the Earth that orbits the Earth with a synodic cycle.

During the revolution, the side of the Moon that is illuminated by the Sun (the day on the Moon) and the side that is not illuminated by the Sun (the night on the Moon) alternately face the Earth.

So, one day on the Moon is equivalent to about half a month (about a day) on Earth.

The moon does not rotate, it always rotates around the earth with one side, and then the other side is dark and the night never sees the light, the main reason is that if he does not rotate the other side, he cannot be exposed to the sun and has no light, so one side of the day is eternal, and the other side of the night is also eternal.

One day of the Moon is equal to about one month of the Earth.

The time it takes for the earth to revolve around the sun is one year, while the time for the moon to revolve around the earth is equal to 27 days on the earth, and the time for the earth to rotate on its axis from west to east is 23 hours and 56 minutes, which is one day and night of the earth; The period of the Moon's rotation is exactly equal to the period of its revolution by one week, so one day of the Moon is equal to one month of the Earth.

The laws of the moon's motion

The Moon rotates around the Earth in days, which is exactly the same as its rotation period, so we can't see the far side of the Moon. This phenomenon, which we call "synchronous rotation", is almost a universal law in the satellite world, and is generally believed to be the result of the long-term tidal action of planets on satellites.

The rotation of the moon also makes the moon have day and night like the earth. Since the time of one rotation of the moon is about equal to one month, the time of one day (one day and night) on the moon is about the same as one month of the earth, that is to say, the time of a day in any part of the moon is equivalent to nearly 14 days of the earth, and the time of night is roughly equivalent to 14 days of the earth.

Due to the Earth's rotation, the Moon can be seen rising in the east and setting in the west every day, but the Moon rises an average of 50 minutes later than the day before. This is because at the same time the next day, due to the relative motion of the Earth and the Moon, the Moon is no longer in its original position, but has orbited the Earth at a certain angle to the east, so the Earth also has to rotate at a certain angle to see the Moon, and this process takes about 50 minutes.
