Eclipse, also known as lunar eclipse, [1] It is a kind of Moon Running into the shadow of the earth Umbra and Penumbra Two parts), could have been sunlight Some or all of the parts illuminated by light cannot be illuminated by direct sunlight, so that Observer Can't see ordinary phase of the moon Of Astronomical phenomenon 。 When a lunar eclipse occurs, the sun, the earth, and the moon are exactly or almost in the same straight line, so the lunar eclipse must occur at the night of the full moon (the 15th, 16th, or 17th lunar calendar), such as Shuowen Said“ solar eclipse Then new moon, eclipse is looking ". "Shuo" refers to the first day of the lunar calendar, and "Wang" refers to the fifteenth day of the lunar calendar Earth shadow be located Earth revolution Track surface（ Ecliptic surface ）Inside, this plane and the lunar orbital plane（ Bai Dao The surfaces are not coincident, and the intersection angle of yellow and white pavement is about 5 degrees; In most full moons, the moon is not in the ecliptic plane, but is either north or south, not in the shadow of the earth. Therefore, not every full moon has a lunar eclipse. There are at least two lunar eclipses in the world every year. [2] [6]
In 2024, two lunar eclipses will occur on March 25 (penumbral eclipse) and September 18 (partial eclipse) respectively.

Lunar eclipse type

Announce
edit
  • There are three types of lunar eclipses
1． lunar eclipse When the whole moon enters the Earth's umbra. The last total lunar eclipse occurred on May 26, 2021.
2． partial lunar eclipse : When only part of the moon enters the Earth's umbra, a partial lunar eclipse will occur before and after it. The last partial lunar eclipse occurred on November 19, 2021.
3． Penumbral eclipse : At this time, the moon only skims over the penumbra of the earth, causing a slight decrease in the luminosity of the moon surface, so it is less noticeable. The last penumbra lunar eclipse occurred on June 5, 2020.
Since the earth's umbra is much larger than the moon's, it also means that the moon will completely enter the earth's umbra area in the event of a total lunar eclipse, so it will never appear Annular lunar eclipse This phenomenon.

Eclipse process

Announce
edit
The beginning of penumbra eclipse after total lunar eclipse: the moon just joined Penumbra Contact is invisible to the naked eye. The process of a formal lunar eclipse is divided into Initial loss 、 Eating both 、 Food gluttony Five stages of rejuvenation and rejuvenation. [1]
1. Beginning of penumbra eclipse: When the moon just contacts the penumbra area, the brightness of the moon surface decreases slightly, but it is difficult to detect with the naked eye.
2. Initial loss (only partial eclipse and total eclipse): marks the beginning of the lunar eclipse. The moon enters slowly from the eastern edge Ground shadow , the first time the umbra of the moon and the earth is circumscribed.
3. Shiji (only total lunar eclipse): The moon enters the Earth's umbra and cuts into it for the first time. The moon just entered the Earth's umbra.
4. Food consumption: The moment when the center of the circular surface of the moon is closest to the center of the Earth's umbra, the front and rear lunar surfaces are copper or dark red. [ reason: sunlight after Earth's atmosphere The light is refracted to the inside, but the deflection degree of each light is different（ dispersion ）, red light deflection is the largest and the closest Earth shadow , reflected on the moon; In addition, due to atmosphere The content of dust and cloud of, Light deflection The degree will vary, so the moon during the total lunar eclipse is dark red, red copper, or orange. In the same way, due to the refraction of the atmosphere, the sunrise and sunset are not white Atmospheric refraction Different degrees, orange or red.]
5. Shengguang (only monthly Total eclipse ）: The moon moves in the Earth's umbra and is inscribed with the Earth's umbra for the second time. The eastern edge of the moon is inscribed with the eastern edge of the Earth's umbra, when the total eclipse phase ends.
6. Rejuvenation (only partial and total lunar eclipses): The moon gradually leaves the Earth's umbra and cuts outward with the Earth's umbra for the second time. The western edge of the moon is circumscribed with the eastern edge of the Earth's umbra, when the whole eclipse process ends. The extent of the moon being eaten is called“ Food points ”It is equal to the ratio of the farthest distance of the edge of the moon wheel going deep into the Earth's umbra to the apparent longitude of the moon at the time of eclipse.
7． Penumbra End of eclipse: When the moon leaves the penumbra, the whole eclipse process officially ends. A partial lunar eclipse has no eclipses and light generation process, and eclipses only represent the time closest to the Earth's shadow. [2]
The degree of lunar eclipse is expressed in eclipse minutes. Eating minutes equals eating time, moon Apparent diameter The ratio of the part entering the umbra at the time of eclipse to the apparent diameter of the moon. If the moon is just inscribed with the umbra, the eclipse score is equal to 1. If the moon goes deeper into the umbra, the eclipse is represented by a number greater than 1. The total eclipse of the moon is greater than or equal to 1. The food score of partial food is less than 1. Penumbral eclipse The eclipses are expressed as the ratio of the part of the moon's diameter entering the penumbra to the moon's apparent diameter. The penumbral eclipse can only be detected by the naked eye when its eclipse fraction is greater than 0.7. [3]
The whole process of lunar eclipse

Time of occurrence

The lunar eclipse must occur in "Wang", and the phase of the moon at this time is the full moon, which usually occurs on a day from the 14th to the 17th lunar calendar. [7] On the 15th and 16th lunar calendar, 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, resulting in a total lunar eclipse. [4]
If only part of the moon enters the Earth's umbra, a partial lunar eclipse will occur. When the moon enters the penumbra of the earth, it should be Penumbral eclipse However, because its brightness decreases so little that it is difficult to detect, it is not called a lunar eclipse, so there are only two types of lunar eclipses: total lunar eclipse and partial lunar eclipse.
All lunar eclipses are in sight (full moon), but not every time there is a lunar eclipse, which is different from every new moon solar eclipse The same is true. The phenomenon that the moon is completely or partially covered by the shadow of the earth. Lunar eclipses usually occur during the solar observation, that is Summer Calendar On the 15th or 16th of every month Earth movement to sunlight And the moon, but not every day Possible Eclipse, because the ecliptic and Bai Dao Between Angle of intersection It exists, so only in the continuous pictures of looking at the moon at night and the moon going through an eclipse, it can be seen that when the earth shadow reaches the intersection of the ecliptic and the white path Observer To watch the eclipse. The number of lunar eclipses per year is generally 2.
Solar Diameter ratio The diameter of the earth is much larger, and the shadow of the earth can be divided into umbra and penumbra. The diameter of the earth is about four times that of the moon Lunar orbit The diameter of the Earth's umbra is still 2.5 times that of the moon. A partial lunar eclipse occurs when the moon is always partially obscured by the Earth's umbra. The total eclipse of the moon can be seen when the moon enters the Earth's umbra.
If the moon enters the penumbra area, the light of the sun can also be obscured. This phenomenon is called penumbra lunar eclipse in astronomy. However, because the sun is still very strong in the penumbra area, it is difficult to distinguish penumbra lunar eclipse with the naked eye in most cases. However, in fact, penumbra lunar eclipse happens frequently. According to observation data, penumbra lunar eclipse, partial lunar eclipse Occurring during the total lunar eclipse percentage About 36.60%, 34.46% and 28.94%. [2]
