The celestial globe is a general term for the celestial globe and the celestial globe. The armillary sphere is an instrument used to measure the spherical coordinates of celestial bodies, while the celestial globe was an instrument used in ancient times to demonstrate celestial phenomena. The armillary sphere and the celestial globe are instruments that reflect the theory of the celestial sphere. The inventor of the armillary sphere is said to be Luo Xiahong from the Western Han Dynasty, who was improved by scientist Zhang Heng during the Eastern Han Dynasty. The earliest existing armillary sphere in China was manufactured during the Ming Dynasty and is displayed at the Purple Mountain Observatory in Nanjing.
