ZHOU HONG NAN,ZHUANG WEIFENG,WANG Yu The Korean Astronomical Society 1996 Journal of The Korean Astronomical Society Vol.29 No.suppl1
From 146 B.C. to A.D. 1760, 363 sets of cometary observations have been recorded in Chinese Ancient Records of Celestial Phenomena. The positions of all recorded comets, or their paths, on the sky are compared. Taking into account the perturbations of all nine planets and using the numerical method of N-body problem, the orbits of well-recorded comets are calculated. Identification of a periodic comet is presented.
