Why doesn t the moon come out during the day? Why can t I see the moon these days?

Up up, west, west, down east, east, east, remember these 4 words, and then know that it is enough to check, this is the 8-character proverb.

I'll help you find a few people, according to this theory, the moon that comes out in the second half of the night can be seen at dawn, and the moon that comes out in the first half of the night can be seen at dusk.

As the moon moves a large distance from west to east in the starry sky every day, its shape is constantly changing, which is called the moon phase. "People have joys and sorrows, and the moon has clouds and sunny days", here the circle and deficiency refer to the "moon phase change": the different images of the moon illuminated by the sun as seen on the earth.

Since the moon itself does not emit light, the half of the sphere facing the sun is a bright area, and the other half of the sphere is a dark area. As the position of the Moon changes relative to the Earth and the Sun, the illuminated side of the Moon is sometimes facing the Earth and sometimes facing away from the Earth; Sometimes the part of the moon facing the Earth is larger, sometimes it is smaller, so that different phases of the moon appear.

Whenever the moon orbits between the sun and the earth, and the hemisphere illuminated by the sun is facing away from the earth, people cannot see the moon on the earth, and this day is called the "new moon", also called the "new moon", which is the first day of the lunar calendar.

After the new moon, the moon follows the direction of the earth's rotation, and the bright area gradually turns to the earth, and the moon can be seen on the earth showing a trace of slender silver hooks, appearing in the western sky, bowing its back towards the sunset, this moon phase is called "moth eyebrow moon", which is the beginning of the lunar calendar.

Three, four. Subsequently, the moon moves away from the sun in the sky day by day, at the beginning of the lunar calendar.

On July and August, half of the bright area facing the Earth, one can see the half moon (convex facing west), and this phase of the moon is called the "first quarter moon".

When the Moon moves in the direction of the Earth's back sun, the lunar calendar.

Ten. Five, ten.

On the sixth and seventeenth, the bright areas of the moon are all facing the earth, and we can see a full moon, and this phase of the moon is called the "full moon", also called "hope".

After the full moon, the west side of the bright area begins to deficit, and it is the lunar calendar.

Two. Ten. On the second and twenty-third, you can see the half moon (convex facing east), and this phase of the moon is called the "last quarter moon". During this period, the Moon moves closer to the Sun and rises in the east in the middle of the night.

After another four or five days, the moon turns into a moth-eyebrow-shaped moon bud with its back arched towards the rising sun, and this moon phase is called the "waning moon".

When the Moon moves between the Sun and the Earth again, the Moon returns to the "New Moon".

This is how the phases of the moon change over and over again. If calculated by the cycle of the moon phase change (that is, the entire process of a moon phase change), from the new moon to the next new moon, or from the full moon to the next full moon, it is a "synodic month", with an interval of about a few days, and the length of a month in the Chinese lunar calendar is determined according to the "synodic month".

Because the Earth rotates and the sunlight is too strong during the day, the Moon reflects the sun's light, so it is invisible.

Because the sunlight is too strong during the day, the moon reflects the sun's light, so it is invisible.

But once I found it in heaven).

In fact, as long as you are determined, from the beginning.

In the same way, if you can see the sky shortly after the sun rises in the second half of the month, you can also see it in the sky, and you can also know that it will not disappear during the day, no matter how bright the blue sky is, it is impossible to cover the moon, except for air pollution.

In fact, the moon is also found during the day. I don't know if you have ever had the experience of seeing the sun and the moon at the same time in the morning. But as the sun gets brighter, the moon's light is obscured.

The moon sometimes comes out during the day, but it's too bright to see.

It is out and visible.

Yes, it can be seen a lot of the time.

Because the moon is basically on the same side of the sky as the sun these days, it cannot be seen at night.

It is now the end of the sixth month of the lunar calendar, and the moon phase is on the last quarter of the month.

Between the waning moon, it rises in the east in the early hours of each day, and it is a large crescent moon. Soon after the sun rises, the sky brightens and the moon is largely invisible.

In the evening, the moon sets before the sun sets, so you can't see the moon at night.

The moon looks like in the lower right corner of the image below.

Moon phase chart.

Reasons why there will be a moon during the day:1. The moon can be seen during the day due to different brightness, which may be due to the different brightness. In the early morning or evening, when the sun is rising or setting, the brightness is low, and the blue sky cannot cover the moon.

2. The sun and moon shine together, and the moon can be seen during the day, which may be the phenomenon of the sun and moon shining together. The period of the Earth's rotation around the Sun is one year, whereas the period of the Moon's rotation around the Earth is twenty-seven days.

3. The shape of the moonThe shape of the moon will change continuously during the course of a month.

1. The brightness is different

The moon can be seen during the day, probably due to the different brightness. In the early morning or evening, when the sun is rising or setting, the brightness is low, and the blue sky cannot cover the moon, so the moon is seen during the day.

2. The sun and the moon shine together

The moon can be seen during the day, which may be a phenomenon of the sun and moon shining together. The period of rotation of the earth around the sun is one year, while the cycle of the moon around the earth is twenty-seven days, and in the process of rotation, the sun and the moon will appear on the horizon at the same time at a certain time, thus forming the sun and moon to shine together.

3. Moon shape

The shape of the moon changes over the course of a month. In the lunar calendar, the moon on the first day of the new year is a thin line, from the second day to the beginning of the new year.

The moon from the sixth and twenty-fourth to the end of the month is like a curved eyebrow, and the beginning of the seventh month.

The moon on the eighth and twenty-third is semicircular, and the ninth moon arrives.

Ten. 4. The moon from 17 to 22 is elliptical, and the lunar calendar.

Ten. The moon of the fifth and sixteenth months is shaped like a disk.

4. The importance of the Earth's rotation

The visibility of the Moon on Earth depends entirely on the position of the Moon in orbit. The Moon orbits the Earth in less than thirty days, and during this time it takes on different shapes in our sky and is usually divided into eight phases.

During a given portion of that time period (approximately at the time of the Full Moon), the Moon rises as the Sun sets, as the Moon and the Sun are opposite in our sky. Thus, at the time of each full moon, the Sun, Moon, and Earth are arranged in the following diagram, and we can see the sun set and the moon rise (on the other side of the horizon) at the same time.

Over time, however, the Moon moves closer and closer to the Sun, until it reaches its closest position to the Sun at about the time of the New Moon, when the Moon rises and sets almost at the same time as the Sun. As a result, the moon becomes less bright at night and more pronounced during the day. Since the Earth is constantly rotating, the Moon appears above the horizon for about 12 hours, which coincides with the 12 hours of the Sun on the horizon, so we can see the Moon throughout the day.

The moon does not come out at night.

There are also during the day, but we can't see it with the naked eye. Because it is obscured by the rays of the sun.

At night, the earth is between the sun and the moon, and there is no sunlight from the sun, so we can see the moon.

In general, we can see the moon at night because the earth turns to the side facing away from the sun to form a dark night, and in the absence of sunlight, the moon reflects the sun's rays, so that we can faintly see the moon appear at night. And because the Earth receives direct sunlight from the sun during the day, we cannot observe the moon with the naked eye during the day.
