3789 Zhongguo

3789 Zhongguo (1928 UF, 1986 QK₁) is an outer main-belt asteroid discovered on October 25, 1928 by Y. C. Chang at Williams Bay. It is one of very few asteroids located in the 2 : 1 mean motion resonance with Jupiter. When first discovered in 1928, Zhongguo was named 1125 China. However, as it was not seen again, its designation was later taken by 1957 UN1, which became 1125 China. When re-discovered in 1986, it was named Zhongguo, which is the Chinese word for China ("中国", Mandarin: Zhōngguó).
