The earliest astronomical works in the world are

The Classic of Shigan Star in the Spring and Autumn Period and the Warring States Period is the earliest astronomical work in the world, which records the operation of the five stars and their operation rules in detail.

Astronomy developed in China during the Spring and Autumn Period and the Warring States Period. During this period, a large number of astronomical monographs and observation records aimed at the emperor's astrology appeared. Among them, Gan De, an astronomer from the State of Chu (Qi), wrote eight volumes of Tian Wenzhi, and Shi Shen, an astronomer from the State of Wei, wrote eight volumes of Tian Wenzhi. Later generations combined these two works into one and named them "Shi Gan Xing Jing", which is the earliest astronomical work in the world. The original has been lost, and now it can only be copied piecemeal in relevant historical books of the same period, such as Kaiyuan Zhan Jing.

The book records the movement of five stars and their haunting laws in detail, and records Europa with naked eyes (Gander record, pointed out by Xizai 198 1, but it is not recognized internationally). The book records the names of more than 800 stars and divides their official positions, and its system has a far-reaching impact on the development of later generations. It is mentioned in the book that solar eclipse and lunar eclipse are phenomena in which celestial bodies block each other. To commemorate the discovery of the stone god, there is a crater named after it on the moon.

According to the research of the China scientists' chair, Gander discovered Jupiter's satellite No.3, nearly 2000 years earlier than Italian Galileo and German Maier. The catalogue determined by Gander and Stone God is the earliest catalogue in the world. There are 120 stars in the book, which is relatively accurate according to the current observation results. It is about 200 years earlier than the first catalogue in Europe-the catalogue of Iba Valley in Greece. Shi Gan Xing Jing was selected as the earliest astronomical work in world record association, China.
