What is the phenomenon of a lunar eclipse and what happens during a lunar eclipse?

A lunar eclipse is a natural phenomenon in which when the Sun, Earth, and Moon are exactly or almost in the same straight line (the Earth is between the Sun and the Moon), the light from the Sun to the Moon will be partially or completely obscured by the Earth, resulting in a lunar eclipse.

For the Earth, the Sun and Moon are 180° apart, so the eclipse must have occurred around the 15th day of the lunar calendar. It is important to note that since the orbits of the Sun and Moon in the sky (called the ecliptic and white paths, respectively) are not in the same plane, but are about 5° angles, only if the Sun and Moon are near the two intersections of the ecliptic and the white path, respectively, will have a chance to form a straight line and produce a lunar eclipse.

1.Total Lunar Eclipse:

When the moon, the earth, and the sun are completely in a straight line, the earth is in the middle of the three, and the entire moon enters the shadow of the earth, and the surface of the moon turns dark red, and a total lunar eclipse will be formed.

During the total lunar eclipse phase, the moon will turn into a mysterious and beautiful "red moon".

2.Penumbral Lunar Eclipse:

When the Moon orbits the Earth, the Moon does not enter the umbra but only the penumbra, which is called a penumbral lunar eclipse. During a penumbral lunar eclipse, the Moon will darken slightly, but its edges will not be blocked by the Earth's shadow.

A penumbral lunar eclipse is an astronomical phenomenon in which the Moon enters the Earth's penumbra, when the Earth blocks part of the Sun's light towards the Moon, and the Moon looks darker than usual, but it is still bright, but its brightness is slightly dim.

During a penumbral lunar eclipse, the lunar surface has a process of going from light to dark and from dark to light, and because the moon is slightly darker than usual, it is less noticeable with the eyes.

3.Partial lunar eclipse:

A partial lunar eclipse occurs when the Moon enters only part of the Earth's umbra;

The process of partial lunar eclipse is divided into three stages: initial loss, eclipse and roundness. First wane: The Moon has just come into contact with the Earth's umbra, marking the beginning of a partial lunar eclipse.

The Moon begins to enter a "shadow" state. Eclipse: The center of the Moon is closest to the center of the Earth's umbra.

The Moon is basically surrounded by "shadows". Roundness: The western edge of the Moon is tangent to the eastern edge of the Earth's umbra, and the whole process of the partial lunar eclipse ends.

At this time, the moon returns to light. The degree to which the Moon is eclipsed is called "eclipse", which is equal to the ratio of the farthest distance between the edge of the lunar ring and the Earth's umbra at the time of the eclipse to the Moon's visual meridian.

The reason for the formation of a lunar eclipse is that the light travels in a straight line, and at some point the earth blocks the sun's rays from shining on the moon.

The Earth and the Moon do not emit light, only the Sun shines, and when the Moon moves between the Earth and the Sun, and the three of them are in a straight line, a lunar eclipse is formed.

A lunar eclipse is: the moon - > the earth - > the sun: a lunar eclipse is formed in a straight line.

What is the difference between a solar and lunar eclipse? What are the three celestial bodies involved in a solar and lunar eclipse? Which is the most common, solar or lunar eclipse? So, have you ever seen a lunar or solar eclipse? What's the difference between the two? Let's take a closer look at these two impressive celestial phenomena.

A lunar eclipse is an astronomical phenomenon.

A lunar eclipse, also known as a lunar eclipse, is a kind of lunar eclipse when the moon moves into the shadow of the earth (the shadow is divided into two parts, umbra and penumbra), the part that can be illuminated by the sun's rays is partially or completely illuminated by direct sunlight, making it impossible for observers on the earth to see the ordinary moon phase.

When a lunar eclipse occurs, the Sun, Earth, and Moon happen to be or almost in the same straight line, so the eclipse must occur on the night of the Full Moon (lunar calendar.

Ten. Five, ten.

6. or 17), as the Shuo Wen says, "the solar eclipse is the new year, and the lunar eclipse is the hope."

The Earth's shadow is located in the Earth's orbital plane (ecliptic plane), which does not coincide with the lunar orbital plane (white plane), and the intersection angle of the yellow and white planes is about 5 degrees. During most Full Moons, the Moon is not in the ecliptic plane, but is either north or south, not in the Earth's shadow, so not every Full Moon eclipse occurs; But there are at least two lunar eclipses around the world every year.

A lunar eclipse is a natural phenomenon formed by the obscuration of light, when the Sun, the Earth, and the Moon happen to be in the same straight line (the Earth is between the Sun and the Moon), the light from the Sun to the Moon will be partially or completely obscured by the Earth, resulting in a lunar eclipse.

There are two prerequisites for the production of lunar eclipses:

1. A lunar eclipse must occur at the location of the moon (i.e., the full moon), that is, the lunar calendar.

Ten. 5. 16 days;

2. The Sun and the Moon are located near the two intersections of the ecliptic and the white path, respectively. Not all Mochizuki will have a lunar eclipse.

Because the orbits of the Sun and the Moon in the sky (called the ecliptic and white paths) are not in the same plane, but have an angle of about 5°9, only if the Sun and the Moon are near the two intersections of the ecliptic and the white path, respectively, have a chance to join in a straight line and produce a lunar eclipse.

The process of lunar eclipse is divided into five stages: initial loss, eclipse, eclipse, rebirth, and recirclement.

First Loss: Marks the beginning of a lunar eclipse. The Moon slowly enters the Earth's shadow from the eastern edge, and the Moon and the Earth's umbra are incised for the first time.

Eclipse: The Moon just enters the Earth's umbra, and the western edge of the Moon is inscribed with the western edge of the Earth's umbra.

Eclipse: At this time, the surface of the moon is red copper or dark red, marking the center of the moon closest to the center of the earth's umbra.

Light: The Moon moves within the Earth's umbra, and the eastern edge of the Moon is intangent to the eastern edge of the Earth's umbra, at which point the total eclipse phase ends.

Round: The Moon gradually leaves the Earth's umbra, and the western edge of the Moon is tangent to the eastern edge of the Earth's umbra, at which point the whole process of the lunar eclipse ends.

So, have you ever seen a lunar or solar eclipse? What's the difference between the two? Let's take a closer look at these two impressive celestial phenomena.

1. Lunar eclipse is a special astronomical phenomenon, which refers to an astronomical phenomenon in which when the moon moves to the shadow part of the earth, some or all of the parts that can be illuminated by the sun's rays cannot be illuminated by direct sunlight, so that observers located on the earth cannot see the ordinary moon phases. When a lunar eclipse occurs, the Sun, Earth, and Moon are exactly or almost in the same straight line;

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