对近地天体2004CK39在类彗星轨道上运行的轨道演化的研究表明，它是地球轨道的四重十字线。如果这颗彗星在过去是一颗活跃的彗星，但现在已经灭绝，那么它可能会形成一股流星流，在地球上产生四次可观测的流星雨，活动在2月和10月。我们已经确定了所有这四个流星雨，这证明了2004CK39是一个休眠或死亡的彗核。
An investigation of the orbital evolution of near-Earth object 2004CK39, moving on a comet-like orbit, shows that it is a quadruple crosser of the Earth’s orbit. If this object were an active comet in the past, but now is extinct, then it might form a meteoroid stream that should produce four observable meteor showers on the Earth, active in February and October. We have identified all four of these showers, which proves that 2004CK39 is a dormant or dead comet nucleus.
