Chinese astronomers begin to catalogue and name the brightest stars.

Star names later categorized in the twenty-eight mansions have been found on oracle bones unearthed at Anyang, dating back to the middle Shang Dynasty (Chinese Bronze Age), and the mansion system's nucleus seems to have taken shape by the time of the ruler Wu Ding (1339-1281 BCE).

Shang astronomers have also sighted Mars and various comets.
