Why does the sun lose first in the west and the east in the east during a lunar eclipse?

So the revolution of the Earth can be ignored and roughly seen as the Sun and the Earth is stationary, just looking at the motion of the Moon, because the Moon moves counterclockwise around the Earth, and from the Earth (if you are in the Northern Hemisphere), the Moon will move towards the Sun from the west (right) and then begin to cover the Sun.

So it looks like the sun is losing money from the west, on the other hand. When moving to the shadow of the earth, the apparent motion of the sun caused by the revolution of the earth is from west to east, and the rotation of the moon around the earth is also from west to east, so when the moon catches up with the sun from west to east, it is the west side of the sun that is blocked by the moon first. During a lunar eclipse, the moon also runs fast, and the moon enters the earth's shadow from west to east, so it is the east side of the moon that loses first.

The moon orbits the earth with a short period and fast angular velocity, while the earth orbits the sun with a long period and a slow angular velocity, so if you look at it from the earth, it is the moon catching up with the sun to form a solar eclipse.

From the perspective of the earth, the apparent motion of the sun caused by the rotation of the earth is from west to east, and the rotation of the moon around the earth is also from west to east, so when the moon catches up with the sun from west to east, it is the west side of the sun that is blocked by the moon first.

During a lunar eclipse, the moon also runs fast, and the moon enters the earth's shadow from west to east, so it is the east side of the moon that loses first. Among natural phenomena, solar and lunar eclipses can be listed as the most famous.

In Japan, there is also a legend that the tengu eats the moon. It doesn't matter whether people believe in these legends or not, but it reflects a strong interest in this natural phenomenon.

This is because the revolution and rotation of the sun and the moon are not the same, so they appear differently.

This is because the sun and the moon have different rotations and rotations, after all, solar and lunar eclipses occur.

It's already magical.

Because where we see the sun, the Earth's moon is caused by the trajectory of the moon.

This has some laws of its own, and the arrangement of nature is clear.

From Earth (if you're in the Northern Hemisphere), the Moon will move toward the Sun from the west (right) before it begins to obscure the Sun.

This is some special natural phenomenon, isn't it, after all, the occurrence of solar and lunar eclipses is already magical.

This is based on the results of certain scientific investigations, and there are very correct aspects.

This is because the geography in which we live is not exactly the same.

After all, the occurrence of solar and lunar eclipses is already magical, do you think this is the case?

I think there are a lot of reasons, don't you think so?

Since the Moon revolves from east to west around the Earth.

Solar eclipse. When it comes.

The Moon passes through the Earth from the east to obscure the Sun.

The part that shades the sun starts from the east.

And a lunar eclipse. , the earth is between the sun and the moon, because it is also from east to west, the part of the moon that disappears first is the west, and then gradually reaches the full moon, so it should be a solar eclipse, the sun loses first to the east, and the moon loses to the west first.

Since the moon revolves from east to west around the earth, when a solar eclipse comes, the moon passes through the earth from the east to block the sun, and the part that covers the sun starts from the east.

During a lunar eclipse, the earth is between the sun and the moon, and since it is also from east to west, the part of the moon that disappears first is the west, and then gradually reaches the whole moon. Therefore, it should be a solar eclipse, where the Sun loses first to the east, and a lunar eclipse, where the Moon loses to the west.

A solar eclipse, also known as a solar eclipse, is the movement of the moon between the sun and the earth, if the three are exactly in a straight line, the moon will block the light of the sun to the earth, and the black shadow behind the moon falls on the earth, and the solar eclipse phenomenon occurs.

In folklore, this phenomenon is called the Tengu Eclipse Day. Solar eclipses only occur at the New Year, when the Moon and the Sun are conjunct. Solar eclipses are divided into partial solar eclipses, total solar eclipses, annular solar eclipses, and total annular eclipses.

1. During a solar eclipse, the moon blocks the middle of the sun and the earth, blocking the sunlight and making the sun look like there is a gap.

2. Since the Moon orbits the Earth from west to east, solar eclipses always begin at the western edge of the Sun's circle.

3. A solar eclipse will only occur when the Moon is between the Sun and the Earth and aligns in the same straight line. This condition is only met when the Moon meets the Sun, that is, at the New Moon (the first day of the New Moon), when the Sun is located at one of the two points of intersection of the Moon's orbit and the ecliptic (the plane of the Earth's orbit around the Sun), that is, at one of the two points at which the Moon cuts the ecliptic.

First, the earth rotates from west to east, and the direction of the sky is up, north, down, south, left, east, right, and west.

Second, on the first day of the lunar calendar, the moon and the sun rise and set at the same time, that is, the moon rises in the morning at this time, so that it is possible to cover the sun.

The solar eclipse first lost to the southeast. The lunar eclipse first loses in the east.

Solar eclipse: Solar eclipse is also known as solar eclipse, which is the movement of the moon to the middle of the sun and the earth, if the three are exactly in a straight line, the moon will block the light of the sun to the earth, and the black shadow behind the moon just falls on the earth to hold the land, and then the solar eclipse phenomenon occurs. In folklore, this phenomenon is called the Tengu Eclipse Day.

Solar eclipses only occur at the New Year, when the Moon and the Sun are conjunct. Solar eclipses are divided into partial solar eclipses, total solar eclipses, annular solar eclipses, and total annular eclipses.

Lunar eclipse: A lunar eclipse is a special astronomical phenomenon that refers to the area between the Moon and the Earth when the Moon moves to the shadow part of the Earth, because the sunlight is blocked by the Earth, and a piece of the Moon is missing. At this time, the sun, the lot, and the moon are exactly on the same straight line of oaks.

Lunar eclipses can be divided into three types: partial lunar eclipses, total lunar eclipses, and penumbral lunar eclipses.
