The ancient Chinese knew Jupiter as the "Suì Star" and established their cycle of 12 earthly branches based on the approximate number of years it takes Jupiter to rotate around the Sun; the Chinese language still uses its name (simplified as 歲) when referring to years of age. By the 4th century BC, these observations had developed into the Chinese [[zodiac]], and each year became associated with a Tai Sui star and god controlling the region of the heavens opposite Jupiter's position in the night sky.
