Effect of a solar eclipse, the difference between a solar eclipse and a solar eclipse

A solar eclipse is when the moon circles the earth and turns between the sun and the earth, if the sun, the moon, and the earth are exactly lined up or close to a straight line, the moon blocks the sunlight that shoots to the earth, and the black shadow behind the moon falls on the earth, and the solar eclipse phenomenon occurs.

A solar eclipse is a condition in which the Earth enters the umbra of the Moon and the Sun is obscured. It occurs when the Sun, Moon, and Earth are in the same straight line. The Moon is between the Sun and the Earth every month, but eclipses cannot be seen every month because the plane of the white channel (the Moon's orbit) is inclination to the Earth's orbit by 5°.

The Moon may be sometimes above or below the ecliptic, so its shadow cannot fall on Earth. An eclipse can only occur when the Sun, Moon, and Earth are in a straight line. If a part of the Earth is within the shadow of the moon, a solar eclipse occurs; There are three types of solar eclipses: total eclipse, partial eclipse, and annular eclipse.

There are certain places on Earth that are located within the shadow cone of the Moon (i.e., within the cardinal shadow), and these places can reach a total solar eclipse. Eclipses are seen where the extracone shadow hits (i.e., where the penumbra is inside). When the Moon is far away from the Earth, the tip of the shadow cone does not reach the ground, and then the edge of the sun is seen from the extension of the cone**, and there is a narrow ring, which is the phenomenon of annular erosion.

Ring erosion can only be encountered a dozen times in a hundred years in Asia, and it is rare to have a chance to meet an annualizer in a small area in hundreds of years. The shadow of the moon casts onto the ground and moves rapidly westward, so that the total eclipse that can be seen in a certain spot is very short, the longest is no more than seven and a half minutes, and the average is about three minutes. The width of the total solar eclipse zone, on average, is about 160 km.

The chance of a total solar eclipse at a certain location is very rare; On average, only once in 360 years. Although the chances of a total solar eclipse are scarce, there are many problems that need to be observed and studied. For example, the determination of the tangent moment of the sun and the moon.

[Word]: Solar eclipse.

Zhuyin]: rì shí

Interpretation]: An astronomical phenomenon in which the moon obscures the sun as seen on Earth. The Moon orbits between the Sun and the Earth, which occurs when the three are close to a straight line.

There are three types of total eclipse, partial eclipse and annular eclipse. There can be up to five solar eclipses per year and at least two per year.

Interpretation]: 1Solar eclipse.

Nothing different! It's a variant! Generally write more about solar eclipses!

A solar eclipse, also known as a solar eclipse, is an astronomical phenomenon in which the moon moves between the sun and the earth, and if the three are exactly in a straight line, the moon will block the sun's light from the earth, and the dark shadow behind the moon falls exactly to the earth, and a solar eclipse occurs.

In folklore, this phenomenon is called the Tengu Skin-Eating 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.

You can't look directly at the sun when observing a solar eclipse, otherwise it will cause temporary blindness, and in severe cases, permanent blindness.

Historical Records: The Book of Heavenly Officials": "Cover the Spring and Autumn Period between the two hundred and forty-two years, and the solar eclipse was thirty-six. "Song Shu Lizhi I":

At the time of conjunction, there may be a sun occultation of the moon, or a lunar occultation of the sun. The moon occults the sun, which obstructs the burning cavity of the solar body, so that the scenery is lost, so it is called a solar eclipse. Tang Liu Kui, "Sui and Tang Jiahua" volume:

The servant shot Su Wei has a very good mirror, and the sun has eclipsed, and the mirror is dark and invisible. Guo Moruo, "Suchang Zheng Lian Ji Xing, July 9th": "Five solar eclipses, the eclipse starts from the first quadrant, and finally it is like a crescent moon. ”。
