Sometimes the sun and the moon are on the same day, why?

Isn't it just that during the day, you can see the sun and the moon hanging in the sky together? It is common to have breakfast or in the evening, and sometimes it can be seen in the afternoon. Moon.

Caused by revolution, it's not a big deal. 1 Why is there a moon and the sun together in the sky, 2 why is it seen mainly in the evening.

It is due to the fact that the Moon revolves around the Earth, and the angle between the Moon and the Earth will change by one week within a month. In fact, as long as this angle is not 180 degrees, there will be times when the moon and the sun are above the ground level. When the sun and moon are above the ground level, if the angle is too small, the moon may not be visible.

One is because the sun is too bright; Another reason is that only the sunny side of the moon is bright, and the sunny side of the moon is too small to face the earth. So it is easy to be noticed only in the evening and early morning.

The moon rises 49 minutes every night. The queen of heaven happened to be back in her original position. This is a lunar synodic month.

It is like the fifteenth lunar moon that rises at six o'clock in the evening and sets at six o'clock in the morning. The next day, sixteenth, the moon rose at 6:49 p.m. and set at 6:49 a.m. Except for the 30th day of the lunar calendar, the first and second days of the lunar calendar, the moon can be seen during the day or at night in these days (when the moon is too close to the sun).

In fact, it is not that there is no chance to see it in these three days, but it is relatively difficult. The sun and the moon shine together.

This is not an uncommon phenomenon at all. Especially on the 8th and 22nd days of the lunar calendar.

It is true that the average distance between the Earth and the Moon is increasing very slowly. But the changes will not be noticeable to the human eye for at least tens of millions of years. If the moon is moving away from the earth at a speed visible to the naked eye, it will escape within a few months.

I think it's because you don't know much about the moon and the lunar calendar. If you look closely, you can also see that the protruding side of the moon is always facing the sun.

Due to the spatial location, the sun and the moon are often shoulder to shoulder, so what is the fuss about the wood. A little knowledge of astronomy basics and a basic geometric imagination will make you understand. At 3 p.m., the moon appears in the eastern sky, which is supposed to be close to the lookout in the first half of the lunar month, and the moon appears in the west sky in the morning, roughly after the lookout day in the late lunar month.

The sun and moon appear at the same time, but the moon is not visible because the light reflected to the moon is less noticeable during the day.

In life, there is often a scene of the sun and the moon shining together. The sun has come out in the morning, and the moon has not yet set. This is mainly related to the trajectory of the Moon around the Earth.

This is a natural phenomenon, and this is because when the earth moves around the sun, and when the moon moves around the earth, the cycle of rotation is completely different, so this is the case in the end.

When the sun is rotated, the cycles are different, so the sun and the moon are on the same day.

Because the earth and the moon are in motion, they will have a very good angle when they are moving, so that the sun and the moon will be the same day.

Depending on the Earth's weather, and according to the Earth's rotation, the Sun and the Moon sometimes appear on the same level, so that we can see both the Sun and the Moon.

At this time, the environment is very good and the visibility is very high. The Sun and Moon appear on the horizon. This may happen.

Because the sun and moon are originally in the sky, but the brightness is relatively high during the day, so the moon cannot be seen, but in fact, the moon is always there.

This is a very natural phenomenon in which the sun and moon appear on the same level as they rotate.

The sun and moon appear at the same time and are a natural phenomenon.

The meteorological department explained that the sun and moon appeared on the horizon at the same time.

Above. Theoretically, if the atmospheric conditions are relatively good, this phenomenon may occur except on the fifteenth day of each month. However, another condition is that the extreme magnitude in the sky (the faintest objects can be seen) cannot be too low, so in general, when the sun rises or is about to set, the brightness of the sky can easily reach this condition.

When the sun and moon are above the earth's surface, if the angle is too small, the moon may not be visible. One is due to the excessive brightness of the sun; Another factor is that the moon is bright only on the sunny side, and the part of the moon facing the earth is too small at the moment. Therefore, it is easy to notice only in the case of dusk and morning.

The moon rises 49 minutes late every day. After a few days, it happened to return to its original position. This is a lunar synodic month.

It is like the fifteenth lunar moon that rises at six o'clock in the evening and sets at six o'clock in the morning. The next day on the sixteenth, the moon rose at 6:49 p.m. and set at 6:49 a.m. Except for the 30th day of the lunar calendar, the first and second days of the lunar calendar, the moon can be seen during this time (when the moon is too close to the sun) or in broad daylight or at night.

In fact, these three days are not completely uneventful, but relatively difficult. The sun and the moon shine together.

This is not an uncommon situation at all. Especially on the 8th and 22nd days of the lunar calendar.

It is true that the Earth-Moon mean interval is widening very slowly. But it will take at least millions of years for people to see it with the naked eye. If the Moon was avoiding the Earth at a rate visible to the naked eye, it would not be a few months before the Moon hit and run.

I think it's because you don't know much about the moon and the lunar calendar. If you look closely, you can still see that the raised side of the moon is always facing the sun.

Because of the interior space, the sun and the moon are often side by side, so there is nothing to fear. A little basic knowledge of astronomy and a basic geometric figure will help you figure it out. At 3 p.m., the moon occurs in the eastern sky, which should be close to the viewing day in the middle of each lunar month, and the moon occurs in the western sky in the morning, which is probably the viewing day in the middle of each lunar month.

Since the angle between the moon and the earth around the earth will change by one week in a month, as long as this angle is not 180 degrees, there will be a situation where the moon and the sun are on the ground level, and another reason is that only the sunny side of the moon is bright, and the sunny side of the moon is too small at this time, so it is easy to be noticed only in the evening and early morning.

The moon has a specific angle to the sun when it revolves around the earth, which will give the moon a good reflection and the sun and moon will appear on the same day.

It may be due to the movement of the earth and the sun, or it may be caused by natural celestial conditions, or it may be that the earth, the sun, and the moon are in the same line.

Answer: Tomorrow.

Solution ideas: 1. "Ming" is "day" and "month", so when the sun and moon are together, it is tomorrow.

2. It is simply impossible for the moon and the sun to be together, so it is "tomorrow" (it is possible in the future) that they will be together.

As for when the sun and moon appear in the sky, it has to do with the rotation of the moon:

On the first day of the lunar month, the moon and the sun rise and set at the same time. The sun and moon are always in the sky at the same time, but the moon phase on that day is the new blue moon, and the dark side of the moon is facing the earth, and people cannot see it.

Then, with each passing day, the Moon moves about 13 degrees eastward, i.e. 52 minutes later than the Sun and 52 minutes later than the Sun. Until the fifteenth day of the lunar calendar, the sun and the moon will appear in the same sky. On the fifteenth day of the lunar calendar, the moon comes out, and the sun just sets, and it will not appear in the sky at the same time.

Fifteen years later, when the sun rises, the moon is still about 13 degrees above the western level, that is, the moon can remain in the sky for 52 minutes after dawn. Each day that passes, the length of stay.

Add 52 minutes. Ninja.

Therefore, except for the fifteenth, there is the phenomenon of the sun and moon in the sky at the same time, but the time of occurrence varies from day to day. Nothing more!

The phenomenon of the sun and moon shining together requires the sun and moon to be above the horizon at the same time. Theoretically, such a phenomenon may occur except for the 15th day of the lunar calendar.

But the second condition is that the extreme magnitude of the sky (the faintest objects that can be seen) cannot be too low, so in general, the brightness of the sky is easy to meet when the sun is rising or setting (even in cities).

Therefore, in the first half of the lunar calendar (after the fourth day of the lunar calendar), the phases of the moon can be seen when the sun sets, from the west to the east in turn.

In the second half of the lunar month (before the twenty-seventh), the moon can also be seen after the sun rises, and it moves from the western sky to the eastern sky in turn.

"The sun and the moon shine together" is actually a normal natural phenomenon, and it is necessary to look at the "sun and moon shine together" scientifically, and don't say that there are superstitions in it. "The sun and the moon shine together" has a close relationship with the moon phase, people with a little scientific common sense know that the moon itself does not shine, it shines by reflecting the sun's light, because the position of the moon relative to the earth and the sun is constantly changing, the side of the moon illuminated by the sun will sometimes face the earth, sometimes carry the earth, and the part towards the earth is sometimes larger, sometimes smaller, and the moon phase change is produced in this way. The direction of the Earth's rotation and the Moon's revolution is from west to east, and the Moon rotates about 30 times during this period.

For example, on October 3, 2007, the "sun and moon shine together" appeared in Hangzhou because it was the twenty-third day of the eighth month of the lunar calendar, according to the law of the change of the phenomenon of "sun and moon shine together": the sun and moon appeared at the same time from early morning to noon on that day, because the moon rose 6 hours earlier than the sun, and the moon was in the west of the sun.

The sun and the moon shine together near noon, just as you say that the sun is in the east and the moon is in the west. These are all normal natural phenomena, and don't be arbitrarily suspicious of good luck.

China is located in the northern hemisphere, and the "sun and moon shine together" is a special phenomenon that occurs in autumn. Seeing the "sun and moon shining together" must also be in the daytime, because there will be no sun at night. In addition, if the clouds can partially block the sunlight but do not shade the moon, the phenomenon of "sun and moon shine together" is more likely to occur in cloudy or cloudy weather.
