When was the largest solar eclipse in history and when was the earliest recorded solar eclipse?

A solar eclipse (the moon between the Sun and the Earth) lasts for a maximum of 7 minutes and 31 seconds. The 1955 solar eclipse that lasted 7 minutes and 8 seconds in West Philadelphia was the longest in recent years. According to **, a solar eclipse lasting 7 minutes and 29 seconds will occur in the Mid-Atlantic region in 2186.

In 1995, a mother and child were photographed during a solar eclipse in Bangkok, Thailand, which was a total solar eclipse in some parts of the country. The longest duration of a lunar eclipse (the shadow of the Moon's movement into the Earth) is 1 hour and 47 minutes.

There will be a solar eclipse at 9:30 on July 22, so don't forget to see it.

1: China has a long history of observing solar eclipses, and some people observed solar eclipses as early as 1948 BC. China had the most advanced astronomical observatory at that time more than 2,300 years ago.

China has always attached great importance to the prediction of solar eclipses, and it is said that an astronomical official of the Xia Dynasty was beheaded to warn those who neglected to report a solar eclipse because he was addicted to alcohol. China has the world's earliest, most complete and richest record of a solar eclipse. There are more than 1,000 records of solar eclipses in ancient books (excluding oracle bone inscriptions) from ancient books (to the Qing Dynasty) alone.

The earliest was a solar eclipse recorded in the Book of Shang in 1948 BC. The "Book of Songs" records in detail the solar eclipse that occurred on September 6, 776 B.C.: "At the turn of October, the sun is hard, and there is an eclipse of the sun.

Astronomers around the world generally recognize that ancient Chinese solar eclipse records have the highest degree of credibility, leaving a precious scientific and cultural heritage for the world. The Xia, Shang and Zhou dynasties in ancient China were difficult to accurately determine due to the lack of accurate written records due to their long history, and the solar eclipse celestial phenomenon is like a fairly accurate historical clock, which can help determine the time of some historical events.

2: A solar eclipse in the ancient West stopped a war, and the most famous story in the West is recorded in 585 BC. Milis fought with the Libyan tribes, and in the middle of the battle, suddenly the sun disappeared, and the two tribes were afraid of the coming disaster, and finally reached a good result, and the two tribes made peace and intermarriage.

As for the phenomenon of solar eclipses, except for the Tahitians, who regard solar eclipses as a positive meaning, other countries have interpreted him in a negative way. For example, more than 600 years ago, when Athens attacked a certain tribe, it was afraid to continue because of the eclipse, because it delayed the attack, but let the enemy take advantage of this time to prepare, and when the Athenian army attacked the enemy, it was defeated.

In China, the first two total solar eclipses were only visible in remote areas. Once in 1980, when it was visible only in the Ruili area of Yunnan on the China-Myanmar border, and the other was after the Spring Festival in 1997, when it was visible on the Sino-Russian border, China's northernmost point of the Mohe River.

At that time, it was still winter, and the temperature was about minus 25 degrees Celsius during the day and minus 40 degrees Celsius at night. Fiber grinding.

The total solar eclipse that came on July 22, 2009 was a good "heavenly opportunity" for China's 500-year observation of the total solar eclipse. It was the most spectacular total solar eclipse of the century, and its occultation zone was rare in terms of its breadth, duration, and population of the area it passed.

However, a total solar eclipse on August 1, 2008, there were only a few remote areas in northwest China in the suitable observation zone. As we all know, solar eclipses are because the moon blocks the sun's rays.

When a solar eclipse occurs, the area blocked by the Moon from sunlight forms a shadow "cone" between the Moon and the Earth, and the Earth's surface grazes its part to see a total solar eclipse.

The earliest record of a solar eclipse in China can be found in "Shangshu Yinzheng": "It is the new moon in autumn and the moon in the season, and Chen Fu is gathered in the ,...... of the room."Blind (blind) play drums, gallop, cover people and walk ....... This was a solar eclipse that took place at the location of the house at that time, and it depicts the panic and drumming of people who did not know the natural laws of the eclipse at that time.

According to research, this solar eclipse probably occurred during the Zhongkang period of the Xia Dynasty, about October 22, 2137 BC.

The earliest record of a solar eclipse abroad is a total solar eclipse in Babylon, which occurred on June 15, 763 BC, much later than the earliest record of a solar eclipse in China.

The world's scariest solar eclipse occurred on June 21, 2020.

On this day, a huge eclipse ring leaps across the globe, creating a visual effect that has never been seen before and amazes observers around the globe. In places like South America, Argentina and Brazil, the largest lunar eclipse observatory in Latin America and South America is maintained for 7 hours.

The eclipse was spectacular, especially between 9 p.m. and 11 p.m. local time: France, the United Kingdom, Germany, Belgium and other European countries witnessed the full shape of the moon.

Formation of a solar eclipse:

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. People in the shadow of the moon on the earth began to see the sun gradually weakening, the sun surface was obscured by a round black shadow, when the sky turned dark, all the brightest stars and planets could be seen in the sky, and after a few minutes, the sun gradually appeared from the edge of the moon's black shadow, and began to produce light and recircle.

Since the Moon is smaller than the Earth, only people in the shadow of the Moon can see the eclipse. A total solar eclipse occurs when the moon blocks the sun completely, a partial solar eclipse occurs when part of the sun is occluded, and an annular solar eclipse occurs when the sun is partially occluded. A total solar eclipse lasts no more than 7 minutes and 31 seconds.

The maximum length of an annular solar eclipse is 12 minutes and 24 seconds. China has the oldest record of solar eclipses in the world, and there have been definite records of solar eclipses more than 1,000 years BC. <>
