The change process of the moon during the Mid Autumn Festival, what are the characteristics of the m

The phases of the moon changeThe order is: Crescent Moon - Eyebrow Moon -First Quarter Moon- gibbous moon - full moon - gibbous moon - last quarter moon - waning moon - new moon, and so on, the moon phase changes periodically, and the cycle is about one month.

The cycle of the phases of the moon is the day, called a synodic month, which is the ** of the month and week in the calendar.

This time is more than the moon.

The time to revolve (sidereal month) is longer because when the Moon revolves around the Earth.

, the Earth is also orbiting the Sun, and a synodic Moon will orbit about (360+360* degrees (the revolution only orbits 360 degrees). So a sidereal month is approximately * 360 = days.

Causes:Since the moon itself does not shine nor is it transparent in the sun's rays.

When illuminated, half of the sphere facing the sun is a bright area, and the other half of the sphere is a dark area (blocked by itself). 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 shiny part facing the Earth is larger, sometimes it is smaller, so that different phases of the moon appear.

It can be simply summarized into two things:

1. The moon does not emit light and is opaque.

2. It is related to the relative position of the moon, earth and sun.

Around the ninth to the fourteenth day of the first month, after the first wind, the moon becomes fuller day by day, and you can see most of the bright hemisphere of the moon, and the moon phase at this time is called "gibbous moon". to the lunar calendar.

Ten. At 5 or 16 o'clock, the moon runs directly opposite the sun on the celestial sphere, and the sun and the moon are 180 degrees apart, that is, the earth is located between the sun and the moon.

Note: The moon revolves around the earth for a "synodic month", and "Shuo" is the first day of the lunar month, when the moon is between the sun and the earth, the moon and the sun have the same ecliptic longitude, and people cannot see the moon facing the sun from the earth.

"Wang" is usually the fifteenth or sixteenth day of the lunar month, when the earth is exactly between the sun and the moon, the yellow longitude difference between the sun and the moon is 180 degrees, and people see the moon rising from the east when the sun goes west, and the moon is the brightest and roundest at this time.

1. The moon of the Mid-Autumn Festival is like a big jade plate, and the luster is as dazzling as the porcelain white complexion of a classical beauty.

2. The moon of the Mid-Autumn Festival is like a bright lantern hanging in the sky, as if it is a guiding lamp placed in the world by the fairy world.

The moon is the roundest in autumn because the tilt between the earth and the sun increases in autumn, and the warm and humid air over the land of China gradually subsides, and at this time, the northwest wind.

It is still very weak, the sand and dust have not risen, the air is exceptionally fresh, the sky is particularly clean, and the moon looks round and large, which is the best time to enjoy the moon.

During the Mid-Autumn Festival, the moon rises at 6:30 p.m.

The Mid-Autumn Festival originated in ancient times, popularized in the Han Dynasty, was stereotyped in the early years of the Tang Dynasty, and prevailed after the Song Dynasty.

The Mid-Autumn Festival uses the full moon to reunite people, as a sustenance of missing hometown, missing relatives, praying for a good harvest and happiness, and becoming a colorful and precious cultural heritage.

Because it is the fifteenth day of the lunar calendar, the moon rises almost after the sun goes down, and it may be earlier than the sunset. So the Mid-Autumn Festival is the time when the moon rises at: at sunset.

Because during the Mid-Autumn Festival, the sun, the earth, and the moon are almost in a straight line, and the earth is in the middle. Therefore, the moonrise is around the time of sunset.

For details, see the 2010 Astronomy Popularization Almanac

On the 24th of 2018, the moonrise time of the Mid-Autumn Festival was 18:02, and the moonrise was at 0:03 on the 25th, and the moonset was at 6:06 in the morning.

So the answer to the question is d sunset.

Because it is the fifteenth day of the lunar calendar.

So the moon rises almost as soon as the sun goes down, probably sooner than the sunset. So the Mid-Autumn Festival is the time when the moon rises at: at sunset.

But I don't know, so I won't tell you.

On the fifteenth day of the lunar calendar, the moon rises almost after the sun goes down, probably earlier than the sunset. So the Mid-Autumn Festival is the time when the moon rises at: at sunset.

The Mid-Autumn Festival is the time of the full moon: the moon turns to the other side of the earth, when the earth is in the middle of the sun and the moon, and the half of the moon illuminated by the sun is exactly facing the earth, and what we see at this time is the full moon, or "hope".

The second quarter moon: after the full moon, the moon rises later and later, and the bright part of the moon is smaller and smaller day by day, and on the twenty-third day of the lunar calendar, the full moon loses half, and the half moon at this time only appears in the eastern half of the sky in the second half of the night, which is the "second quarter".

Towards the end of the month, the Moon will rotate again between the Earth and the Sun, and the waning Moon will rise again in the east shortly before sunrise. On the first day of the next month, it is Shuo again, and a new cycle begins.
