The origin of constellations

1, the origin of western constellations

In 270 BC, the Greek poet Aratus wrote Things, in which 47 constellations were mentioned. From the star regions recorded in Celestial Bodies, we can know that due to precession, the South Pole in the period described in the book is not consistent with the current South Pole, so it can be inferred that the starry sky recorded in the book is before 2000 BC.

At the same time, the blank area of the starry sky record indicates that the observer should be near 35 to 36 north latitude. So some people think that the practice of dividing the starry sky into constellations originated from Babylon and Sumer in Mesopotamia, and the constellations of Greece and Egypt may have been introduced from this area.

2. The constellation origin of China.

In ancient China, the sky was divided by star officials. The earliest records of star officials are Sima Qian's Historical Records and Tian Guan Shu, among which 9 1 has more than 500 star officials. By the Sui Dynasty, there were 283 star officials recorded in Song of Heaven, belonging to one of the three yuan or twenty-eight lodging houses.

Sanyuan refers to the three regions surrounding the Arctic sky, namely Ziweiyuan, Taiweiyuan and Tianshiyuan, which are divided into four elephants around the ecliptic and the celestial equator, and each elephant is subdivided into seven regions of the four elephants, collectively called 28 nights. In ancient China, the lunar calendar was used as a calendar year. Because the moon rotates once around the earth on the 28th of every month, it is called a "shelter" or "shed" when it passes through an area every day.

At the end of the Ming Dynasty, due to the influence of western learning spreading to the east, Xu Guangqi compiled the almanac of Chongzhen with reference to the data of European astronomy, adding 23 star officials near Invivo.
