As early as in Spring and Autumn Period (chūn qiū shí qī 春秋しゅんじゅう时期) and the Warring States Period (zhàn guó shí qī 战国时期), Chinese people had made great achievement in astronomy. Based on their long-time observation of the celestial phenomena, Gan De (gān dé 甘あま德とく) of the State of Qi (qí guó 齐国) wrote a work titled Astronomy and Astrology (tiān wén xīng zhàn 天文てんもん星ぼし占うらない) in eight volumes, and Shi Shen (shí shēn 石せき申さる) of the State of Wei (wèi guó 魏ぎ国こく)wrote his Astronomy (tiān wén 天文てんもん), also in eight volumes. The later generations combined their books, naming it Gan and Shi’s Celestial Book (gān shí xīng jīng 甘あま石せき星ほし经), which is the earliest astronomic work in the world.

Gan and Shi’s Celestial Book is the regarded as the earliest astronomic work in the world. It boasts a record of the names of over 800 stars, the positions of 121 which have been ascertained. Gan De discovered Jupiter's moon with the naked eye, 2,000 years earlier than the Italian astronomer Galileo, who discovered it with an astronomical telescope in 1609. Shi Shen discovered the reason for solar and lunar eclipses. A crater on the moon has been named after Shi Shen. Besides, the movement of five planets—Jupiter (mù xīng 木星もくせい), Mars (huǒ xīng 火星かせい), Saturn (tǔ xīng 土星どせい), Venus (jīn xīng 金星きんぼし), and Mercury (shuǐ xīng 水星すいせい) and the rule dictating their appearances were also recorded. In later generations, many astronomers referenced the data from Gan and Shi’s Celestial Book when they measured the place and movement of the sun, the moon and the other planets. Thus, Gan and Shi’s Celestial Book is of great significance in the history of astronomy in China and the whole world.
