Leonids shower a temperamental rock star

狮子座流星雨彰显摇滚明星气质

Among the annual sky-shows , the leonids shower is like a temperamental rock star : in most years it delivers a modest show , with rates of about 15 shooting stars an hour .

从年度天文观测结果来看，狮子座流星群看来是一个变化无常的流星群：在大部分的年份它流星数量适度，一般稳定于每小时出现15颗流星左右。

Like other meteor showers , such as the perseids and the orionids , the leonids happen when earth plows through a trail of debris left in the wake of a comet orbiting the sun .

就像英仙座、猎户座等其他星座的流星雨一样，狮子座流星雨发生的时候，地球碎片在绕太阳彗星后面留下一串轨道。

I have enjoyed the same experience swaying and bathing the leonids shower in november .

我曾在11月的狮子座流星雨里经受过这种摇摆不定的经验。

In other years , however , the leonids can suddenly erupt in spectacular meteor storms , with rates of more than a thousand meteors an hour .

然而在另一些年份，狮子座流星群可以突然暴风骤雨般在每小时爆发出远远超过一千颗以上的流星。
