A total solar eclipse, a partial solar eclipse, or an annular solar eclipse have the least chance of

Total Solar Eclipse: A total solar eclipse occurs when the moon's rings completely obscure the circular surface of the Sun. (When the Moon is near perigee, the moon's umbra can reach the Earth, and a total solar eclipse is visible to the human eye).

Partial solar eclipse: When the Moon is around apogee, the moon's umbra does not reach the Earth, so there cannot be a total solar eclipse, but only a partial solar eclipse.

Annular solar eclipse: When the moon reaches near aphelion, the spire of its umbra cone does not reach the Earth, resulting in the visual effect that the moon's rings appear to be a little smaller than the circle of the Sun. Therefore, at this time, the moon cannot cover the sun, and the sun's halo is set around the lunar ring, which is called an annular solar eclipse.

Personally, I think that the probability of a partial solar eclipse is the largest, and it is also the largest observation range;

A total eclipse can only be seen in certain areas, so some places can only see it once in hundreds of years;

An annular eclipse occurs only when the Moon is at apogee (the Moon's orbit is also elliptical) and is therefore least likely.

The probability of a partial solar eclipse is the greatest, followed by a total solar eclipse, and the annular solar eclipse is the smallest. It's all comparative.

In fact, all three are very small.

Partial solar eclipse...

Odds ratio: Partial solar eclipse >> Total solar eclipse >> annular solar eclipse.

A total solar eclipse is the least likely to occur, and a partial solar eclipse is the most likely.

Both the Earth and the Moon are non-luminous celestial bodies that drag a long shadow on the side facing away from the Sun when illuminated by the sun's rays. When the Moon orbits between the Sun and the Earth, if the Sun, the Moon and the Earth are exactly in or close to the same straight line, the Moon shadow extends all the way to the Earth's surface, and the eclipse can be seen in the area and area swept by the Moon shadow. The dark shadow that obscures the sun is the moon.

The Moon orbits between the Sun and the Earth on the first day of the lunar month, so the eclipse must occur on the New Year. But not every New Year's Day has a solar eclipse. Because there is an angle of about 5° between the orbital plane of the Moon and the orbital plane of the Earth, although the Moon is between the Sun and the Earth on most New Lunar New Days, the three celestial bodies are not in a straight line.

Solar eclipses can be divided into three types: total solar eclipses, partial solar eclipses, and annular solar eclipses. The different types of solar eclipses are mainly related to the distance between the sun, the earth, and the moon, and the degree to which they are approximately in a line.

The reason for the formation of a lunar eclipse is relatively simple, that is, when the moon moves into the shadow area of the earth with the sun away from the sun (umbra), the moon is obscured by the earth's shadow, and a lunar eclipse occurs.

During a lunar eclipse, the Earth is between the Sun and the Moon, so the lunar eclipse must occur at the location of the Moon (i.e., the Full Moon), which is the lunar calendar.

Ten. 5.16 days. However, since the Earth's orbital plane and the Moon's orbital plane are not in the same plane, the Moon does not enter the Earth's shadow every month, so it is impossible for a lunar eclipse to occur every moon.

There are two types of lunar eclipses: total lunar eclipses and partial lunar eclipses. During a total lunar eclipse, the moon falls into the Earth's shadow cone, and the inhabitants of half the world (the night side) can see the total lunar eclipse. However, a closer look reveals that the moon is not completely dark during a total lunar eclipse, and the surface of the moon is mysteriously bronze.

This is caused by the Earth's atmosphere refracting a small amount of sunlight onto the moon (with more red light). During a partial lunar eclipse, only a part of the moon always enters the Earth's shadow cone, and the Earth's shadow obscures only a portion of the moon.

The lunar eclipse process takes longer than the solar eclipse, and the total eclipse phase of the lunar eclipse is much longer than the total solar eclipse. Theoretically, the longest total solar eclipse has a total eclipse phase of only 7 and a half minutes (the whole process can be up to 2 hours), while the total eclipse phase of a total lunar eclipse can last more than 1 hour (the whole process can be more than 3 hours).

Annular solar eclipse: occurs when the central part of the sun is dark and the edges are still bright, forming a halo. The reason for this is that the Moon is far away from the Earth, and the Moon's umbra cannot reach the ground and its extension passes through the ground, and people in the area of the umbra extension (artifact zone) of the Moon's shadow can see the annular solar eclipse.

Total solar eclipse: Occurs when the sun's light is completely obscured by the moon. It occurs when the Sun is close to a point where the Moon's orbit meets the Earth's orbit, while the Moon is at the farthest point from this point.

Only when a total solar eclipse occurs is it possible to observe the vague corona (coronal layer) with the naked eye. A total solar eclipse only occurs when the Moon is at perigee.

Partial solar eclipse: When it happens, part of the Sun will be blocked by the Moon. The Moon is between the Earth and the Sun, forming a shadow on Earth.

The shadow of the moon can be divided into three parts: umbra, penumbra, and pseudoumbra. The observer sees in the penumbra that the Sun is partially obscured by the Moon. Usually a partial solar eclipse occurs in conjunction with other eclipse phases, such as a total solar eclipse or annular solar eclipse or total annular solar eclipse.

Solar eclipses can be divided into three types: partial solar eclipses, total solar eclipses, and annular solar eclipses. The difference between a partial solar eclipse and a total solar eclipse is that the position of the earth in the shadow of the moon is not the same, and the type of eclipse is related to the structure of the moon's shadow and the position of the earth in the shadow of the moon at the time of the eclipse.

There are three areas of the moon's shadow: the cone-shaped dark zone that extends directly from the moon is the moon's umbra, where no sunlight can reach it. The cone-shaped dark area that extends from the umbra is called a pseudoumbra and can only be reached by light rays from the surrounding edges of the sun.

The diagonal area around the umbra and pseudoumbra is the penumbra, which is partially accessible by the sun's rays. If only the penumbra of the moon falls to the ground during a solar eclipse, the inhabitants of the area can only see a part of the solar wheel missing, which is a partial solar eclipse.

When the moon's umbra falls to the ground, residents of the umbra can see that a total solar eclipse has occurred. Only the pseudo-umbra of the moon reaches the earth, only the ** part of the sun wheel is dark, and the sun becomes a bright ring, which is an annular solar eclipse.

Thus, during a solar eclipse, the observer sees the Sun in its entirety obscured by the Moon in the umbra range, which is called a total solar eclipse. The observer sees the sun partially obscured by the moon in the penumbra, which is called a partial solar eclipse. There is a halo left around the perimeter, which is called an annular solar eclipse.

The difference between a partial solar eclipse, a total solar eclipse, and an annular solar eclipse is that the sun, the earth, and the moon are moving at different distances. An annular solar eclipse is because the Moon is between the Sun and the Earth, and the Moon is far away from the Earth, so people on Earth can only see the part of the Sun that is not covered by the Moon, and what they see is the outer wheel of the Sun.

Total solar eclipse is also because the Moon is between the Earth and the Sun, but the Moon is closer to the Earth, and the Moon blocks the Sun, so people on Earth can't see the Sun.

Partial solar eclipse refers to an astronomical phenomenon in which when the Moon orbits between the Earth and the Sun, and when the Earth orbits to the penumbra of the Moon, part of the Earth is covered by the penumbra on the outer side of the Moon's shadow, and part of the Sun seen in this area is blocked by the Moon.

The essence of an annular solar eclipse is actually because the Moon is far away from the Earth, the Moon's umbra cannot reach the ground, and its extension line passes through the ground, and people who are in the area of the umbra extension of the moon's shadow can see the annular solar eclipse.

The Moon is a phenomenon in which the Moon is between the Earth and the Sun, forming a shadow on the Earth.

The shadow of the moon can be divided into three parts: umbra, penumbra, and pseudoumbra. The orbit of the Moon around the Earth and the orbit of the Earth around the Sun are not perfectly circular, so the distance between the Sun and the Moon and the Earth is sometimes close and sometimes far. Thus, during a solar eclipse, the observer sees the Sun in its entirety obscured by the Moon in the umbra range, which is called a total solar eclipse. The observer sees the sun partially obscured by the moon in the penumbra, which is called a partial solar eclipse. The observer sees the middle part of the Sun obscured by the Moon in the pseudoumbra, which is called a partial solar eclipse; There is a halo left around the perimeter, which is called an annular solar eclipse.

When the Moon orbits the Earth until the Sun rises and sets almost at the same time as the Sun and the Earth, the Moon cannot be seen from the Earth, which is called the New Year, and the solar eclipse phenomenon occurs at the New Year. The cycle of the new is about a few days. But not every other day, a solar eclipse occurs because the plane of the Moon's orbit around the Earth and the plane of the Earth's orbit around the Sun do not coincide exactly, with 5°9 in between'The average angle.

Therefore, a solar eclipse occurs only when the Sun is within a certain angle of the intersection of the two orbital planes.

Refers to the basic process of a total solar eclipse.

The process of a total solar eclipse can include the following five periods: the first loss, the first loss, the eclipse, the rebirth, and the rebirth.

First loss. Since the Moon orbits the Earth from west to east, the eclipse always begins at the western edge of the Sun's circle. When the eastern edge of the moon first touches the circular surface of the sun (that is, the moment when the eastern edge of the lunar surface and the western edge of the lunar surface are tangent), it is called the first wancing.

The first waning is the moment when the eclipse process begins.

Eat both. From the beginning of the loss, it is the partial eclipse stage. As the moon continues to move eastward, the part of the sun's circle that is obscured by the moon gradually increases, and the intensity and heat of sunlight decrease significantly.

When the eastern middle edge of the lunar surface is intangent to the eastern edge of the solar surface, 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.

Eat very much. After the eclipse, the lunar wheel continues to move eastward, and when the center of the lunar wheel and the center of the sun are closest to each other, the eclipse is reached.

Shine. For partial solar eclipses, an eclipse is the time when the Sun is most obscured by the Moon. The moon continues to move eastward, and the moment when the western edge of the lunar surface and the western edge of the solar surface are intangent is called shengguang, which is the moment when the total solar eclipse ends.

Before the raw auction of Zheng Guang will take place, the phenomenon of diamond rings and pearls will appear on the western edge of the sun again, but they will soon disappear. Then a glimmer of dazzling light was shot on the western edge of the sun, and the chromosphere, heliocord, corona and other phenomena that could have been seen during a total solar eclipse were quickly disappeared into the sun, and the stars disappeared, and the sun shone on the earth again.

Round. After the light is generated, the lunar surface continues to move away from the solar surface, and the obscured part of the sun gradually decreases, and the moment when the western edge of the lunar surface tangent to the eastern edge of the solar surface is called a double circle. At this time, the sun takes on the shape of a disk again, and the entire total solar eclipse process is over.

Pellet beads diamond ring.

When the sun is about to be completely blocked by the moon, an arc of diamond-like light suddenly appears on the eastern edge of the sun's surface, like the striking sparkle on a diamond ring

ring), and at the same time in an instant formed as a string of luminous bright spots, like a string of brilliant pearls hanging high in the dark sky, this phenomenon is called pearl eclipse, the British astronomer Berey was the first to describe this phenomenon, so it is also called Baily

beads）。This is due to the fact that there are many rugged peaks on the surface of the moon, and when sunlight hits the edge of the moon, the phenomenon of Bere-bead is formed. The time for the pearl to appear is very short, usually only a second or two, and then the sunlight is completely obscured and a total solar eclipse occurs.
