The main processes of total solar and lunar eclipses

The first loss, the food is both, the food is very much, and the circle is round.

The evolution of the total lunar eclipse on the evening of January 31.

The process of a total solar eclipse can be divided into five periods: the first loss, the eclipse, the eclipse, the light, and the round.

1. Initial waning: When the eastern edge of the moon just touches the circular surface of the sun, it is called the initial waning. The first waning is the moment when the eclipse process begins.

2. Eclipse: When the eastern edge of the lunar surface and the eastern edge of the solar surface are intangent, it is called an eclipse. At this time, the entire circle of the sun is obscured, so the eclipse is the moment when the total solar eclipse begins.

3. Eclipse: After the eclipse, the moon wheel continues to move eastward, and when the center of the moon ring and the center of the sun are closest to each other, the eclipse is reached.

4. Generating light: The moon continues to move eastward, and the moment when the west side of the lunar surface and the western edge of the solar surface are intangent, it is called shengguang, which is the moment when the total solar eclipse ends.

5. Rounding: After the light, the moon continues to move away from the sun, and the part of the sun that is shaded gradually decreases, when the west edge of the moon surface and the east edge of the sun surface tangent, it is called a circle.

[The process of a total lunar eclipse].It is divided into five stages: initial loss, eating, eating, rejuvenating, and rejuvenating.

1. First loss: The moon has just touched the earth's umbra, marking the beginning of the lunar eclipse.

2. Eclipse: The western edge of the moon is inscribed with the western edge of the earth's umbra, and the moon just enters the earth's umbra.

3. Eclipse: The center of the Moon is closest to the center of the Earth's umbra.

4. Generating light: The eastern edge of the moon and the eastern edge of the Earth's umbra are intangible, and the total eclipse phase ends.

5. Rounding: The western edge of the moon is tangent to the eastern edge of the Earth's umbra, and the whole process of the lunar eclipse ends.

[Differences in the process of total solar eclipse and total lunar eclipse].

1. The eclipse starts on the west side and ends on the east side; The lunar eclipse begins on the east side and ends on the west side.

2. During a total solar eclipse, the sun is not visible; During a total lunar eclipse, the Moon is visible and appears red because the Earth's atmosphere refracts some of the red light onto the Moon.

1. A total solar eclipse is a type of solar eclipse, that is, an astronomical phenomenon in which the sun is obscured by all the moon's macros. If the Sun, the Moon, and the Earth are aligned in or close to a straight line, the Moon blocks the sunlight that hits the Earth, and the dark shadow behind the Moon falls on the Earth, and a solar eclipse occurs. Total solar eclipses are divided into five stages: initial loss, eclipse, eclipse, regeneration, and recovery.

2. A total lunar eclipse is a type of lunar eclipse, which occurs when the entire moon completely enters the earth's umbra. in the lunar calendar.

Ten. 5. 16. The moon moves in the opposite direction to the sun. If the center of the Earth and the Moon are roughly in the same straight line, the Moon will enter the Earth's umbra, resulting in a total lunar eclipse.

1. The reason for the formation of a lunar eclipse is that when the moon moves to the shadow part of the earth, the area between the moon and the earth will be blocked by the earth because the sunlight is blocked, and the moon will be missing. The Sun, Earth, and Moon at this time happen to be (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. A partial lunar eclipse occurs when the Moon enters only part of the Earth's umbra; The diameter of the Earth's umbra is still twice that of the Moon. Therefore, when the center of the Earth and the Moon are roughly in the same straight line, the Moon will completely enter the Earth's umbra, resulting in a total lunar eclipse.

3. And if the moon is always only partially covered by the earth's umbra, that is, only part of the earth's umbra, a partial lunar eclipse will occur. There will be no annular lunar eclipse on the Moon. Because the volume of the Moon is smaller than that of the Earth, the Earth's umbra region does not occur.

Lunar eclipses generally occur twice a year, with a maximum of 3 occurrences and sometimes none at all.

When the moon, the earth, and the sun are completely in a straight line, the earth is in the middle, and the entire moon enters the shadow of the earth, and the surface of the moon turns dark red, forming a total lunar eclipse. The process of a total lunar eclipse is divided into five stages: initial loss, eclipse, eclipse, rebirth, and recirclement. During a total lunar eclipse, only part of the sunlight is refracted by the Earth's atmosphere and hits the Moon, showing a "red moon".

There are three types of lunar eclipses: partial lunar eclipses, total lunar eclipses, and penumbral lunar eclipses. A partial lunar eclipse occurs when the Moon enters only part of the Earth's umbra; And when the entire Moon enters the Earth's umbra, a total lunar eclipse occurs. As for the penumbral lunar eclipse, it means that the moon only passes over the penumbra of the earth, causing a very slight decrease in the brightness of the lunar surface, and it is difficult to see the difference with the naked eye.

When does a total lunar eclipse occur

A total lunar eclipse generally occurs during the lunar calendar.

Ten. 5 and 16, when the Moon moves in the opposite direction to the Sun. At this time, if the center of the Earth and the Moon are roughly in the same straight line, the Moon will enter the Earth's umbra and produce a total lunar eclipse.

During a total lunar eclipse, the Earth, the Moon, and the Sun are in the middle

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

The main differences between total solar and lunar eclipses are different concepts, different periods and occurrences, and different influences, and the differences between the two are obvious.

First, the concept is different.

1. Total solar eclipse: A total solar eclipse is one of the four types of solar eclipses, when the sun's photosphere is completely obscured by the moon, and the originally bright solar disk is obscured by a black lunar shadow.

2. Total lunar eclipse: an astronomical term, it is a kind of lunar eclipse, when the moon, the earth, and the sun are completely in a straight line, the earth is in the middle, and the entire moon enters the shadow of the earth, and the surface of the moon turns dark red, forming a total lunar eclipse.

Second, the occurrence cycle and occurrence time are different.

1. Total solar eclipse: Although a total solar eclipse can occur in some parts of the earth every 18 months on average, a total solar eclipse is still very rare. It is estimated that a total solar eclipse must be observed at an average interval of 370 years at any given location.

A total solar eclipse will not last longer than 7 minutes and 31 seconds, which is generally shorter.

2. Total lunar eclipses: Lunar eclipses occur at least twice a year around the world. Compared to a solar eclipse, a lunar eclipse (from the Moon entering the Earth's shadow to exiting the Earth's shadow) is very long, taking an average of several hours.

Third, the impact is different.

1. Total solar eclipse: When a total solar eclipse occurs, the local temperature usually drops by at least 20 degrees. When 99% of the sun's surface is covered, the phenomenon of morning and dusk shadowing can be seen.

2. Total lunar eclipse: A total lunar eclipse has a certain impact on artificial celestial bodies powered by solar sail panels. China's lunar satellite Chang'e-1, which was launched on October 24, 2007, faced the test of its first total lunar eclipse at the end of February 2008, meeting the temporary "energy" crisis and low temperature test.
