4776 Luyi (1975 VD) is a main-belt asteroid discovered on November 3, 1975 by Harvard University researchers at the Harvard College Observatory.The asteroid is named for a town in the eastern Henan province of China that was the birthplace of Laotze, founder of Taoism,^[2] because the astronomer C.Y. Shao, a long-time participant in the minor planet program at Harvard, came from that town. His son was also named for it.
