Shemaker-Levy9彗星撞击木星的轰动事件令人类更关心彗星撞击地球的问题,接近地球的彗星尤其引人注意,1995年发现了Hale-Bopp彗星,预报它在1997年3月23日从离离地球1.98×10z^8km飞过去,可能比哈雷彗星10倍,甚至100倍,1996年1月30日发现的Hyakutake彗星却先飞来,3月25日从离地球1.530×10^7km飞过去,成为1556年以来见到的最亮彗星。 展开更多

This leads to the impression that the splitting of Comet Hyakutake on a small scale occurred frequently. Data analysis points to a rotation period of about 6.2h if the fragments of April 11 are the condensations within a jet. 展开更多
