China-Astronomy 1

The ancient Chinese invented the first planetarium, which was actually made by an emperor. The planetarium was a big enclosed place with stars and constellations on the inside. The person using the planetarium would sit in a chair that was hanging from the top of the enclosed dome.


To the ancient Chinese, solar ecliA solar eclipse of 16 June 763 BC mentioned in an Assyrian text is important for the Chronology of the Ancient Orient.


By 2300 BC, ancient Chinese astrologers, already had sophisticated observatory buildings, and as early as 2650 BC, Li Shu was writing about astronomy. Observing total solar eclipses was a major element of forecasting the future health and successes of the Emperor, and astrologers were left with the onerous task of trying to anticipate when these events might occur. Failure to get the prediction right, in at least one recorded case in 2300 BC resulted in the beheading of two astrologers. Because the pattern of total solar eclipses is erratic in any specific geographic location, many astrologers no doubt lost their heads. By about 20 BC, surviving documents show that Chinese astrologers understood what caused eclipses, and by 8 BC some predictions of total solar eclipse were made using the 135-month recurrence period. By AD 206 Chinese astrologers could predict solar eclipses by analyzing the Moon's motion.pses meant that dragons were devouring the sun.
