Asteroid was named after former Nanking Rotarian Dr. Ching-Sung Yu ~ 南京紫金山天文臺創建人南京扶輪社余青松博士

Asteroid 3797 was named after Dr. Ching-Sung Yu (1897–1978), a Chinese-American astrophysicist and charter member of the Nanking Rotary Club (1934). Born in Xiamen, Fujian Province, Yu earned degrees in civil architecture and astronomy from Lehigh University, University of Pittsburgh, and the University of California, Santa Cruz. He conducted pioneering spectrophotometric studies of 91 stars at Lick Observatory in the 1920s. Returning to China in 1927, he founded the Purple Mountain Observatory (南京紫金山天文臺) in Nanking and served as its first director. Yu also helped establish the Yunnan Observatory and held leadership roles with Academia Sinica and the Chinese Astronomical Society. After World War II, he moved to North America, teaching at the University of Toronto and directing the Williams Observatory at Hood College until retirement. Discovered in 1987 by Oak Ridge Observatory, asteroid 3797 orbits within the main asteroid belt, honoring Yu’s contributions to astronomy and Rotary history.

O asteroide 3797 foi nomeado em homenagem ao Dr. Ching-Sung Yu (1897–1978), astrofísico sino-americano e membro fundador do Rotary Club de Nanking (1934). Nascido em Xiamen, província de Fujian, Yu obteve diplomas em arquitetura civil e astronomia pela Lehigh University, University of Pittsburgh e University of California, Santa Cruz. Realizou estudos pioneiros de espectrofotometria em 91 estrelas no Observatório Lick na década de 1920. De volta à China em 1927, fundou o Observatório da Montanha Roxa (南京紫金山天文臺) em Nanking, servindo como seu primeiro diretor. Yu também ajudou a fundar o Observatório de Yunnan e ocupou cargos de liderança na Academia Sinica e na Sociedade Astronômica Chinesa. Após a Segunda Guerra Mundial, mudou-se para a América do Norte, ensinando na Universidade de Toronto e dirigindo o Observatório Williams no Hood College até se aposentar. O asteroide, descoberto em 1987 pelo Oak Ridge Observatory, honra suas contribuições para a astronomia e a história do Rotary.

小行星3797以余青松博士（1897–1978）的名字命名，他是中美天体物理学家，也是南京扶轮社（1934年）创始会员。余博士生于福建厦门，曾在理海大学、匹兹堡大学和加州大学圣克鲁兹分校获得土木建筑和天文学学位。1920年代，他在李克天文台开展了先锋性的91颗恒星光谱测量研究。1927年回国后，创立了南京紫金山天文台（南京紫金山天文臺），并任首任台长。余博士还参与云南天文台的建立，担任中央研究院和中国天文学会领导职务。二战后移居北美，曾在多伦多大学任教，并任霍德学院威廉斯天文台台长直至1967年退休。该小行星于1987年由奥克里奇天文台发现，主带轨道，纪念余博士对天文学及扶轮史的贡献。
