Zhu Jin (astronomer)
Zhu Jin (; born April 24, 1965), is a Chinese astronomer. He is the current curator of Beijing Planetarium. Early life Zhu Jin was born on April 24, 1965, in Beijing, China, with his ancestral home (Chinese), ancestral home in Lantian County, Shaanxi. He enrolled in the Department of Astronomy of Beijing Normal University and graduated in July, 1985. After that he continued studying astronomy in Nanjing University and got his Ph.D. in July, 1991. He worked as assistant researcher, associate professor and researcher in succession in Beijing Astronomical Observatory (now part of National Astronomical Observatory of China, National Astronomical Observatory) of Chinese Academy of Sciences from July 1991 to September 2002, and especially as a postdoctoral researcher between May 1992 and April 1994. He moved to Beijing Planetarium in September 2002, since when working as curator. Academic achievements Zhu Jin's major achievements in astronomy lies in the research of asteroids. ...

Comet Zhu–Balam
Comet Zhu–Balam (C/1997 L1) is a long-period comet first identified by David D. Balam on June 8, 1997 and originally photographed by Zhu_Jin_(astronomer), Jin Zhu on June 3, 1997. The comet is estimated at 10 kilometres in diameter with a period of approximately 36,800 years. Given the orbital eccentricity of this object, different Epoch (astronomy), epochs can generate quite different heliocentric unperturbed Two-body problem, two-body curve fitting, best-fit solutions to the aphelion distance (maximum distance) of this object. For objects at such high eccentricity, the Suns Barycentric coordinates (astronomy), barycentric coordinates are more stable than heliocentric coordinates. Using JPL Horizons On-Line Ephemeris System, JPL Horizons the barycentric orbital elements for epoch 2015-Jan-01 generate a semi-major axis of 1100 AU and a period of approximately 36,800 years.
