Xi Zezong
Traditional Chinese席澤宗
Simplified Chinese席泽宗

Xi Zezong (June 6, 1927, Yuanqu, Shanxi – December 27, 2008, Beijing) was a Chinese astronomer, historian, and translator.[1][2] He was a member of the Chinese Academy of Sciences, and an awardee of the Astronomy Prize.

He identified a possible reference to one of the Galilean moons of Jupiter in the fragmentary ancient works of the 4th-century BC Chinese astronomer Gan De, who may have made observation of either Ganymede or Callisto in summer 365.[3][4]

Honors

Asteroid 85472 Xizezong, discovered by the Beijing Schmidt CCD Asteroid Program in 1997, was named in his honor.[5] The official naming citation was published by the Minor Planet Center on April 2, 2007 (M.P.C. 59388).[6]
