If the meteors originate in Comet Halley, why are they called the Orionids?
如果流星来源于哈雷彗星,那么为什么会叫猎户座流星群呢?
This was expected, as mid-October is the time of year for the Orionids Meteor Shower.
这就是人们所期待的,十月中旬就是每年的猎户座流星雨时间。
So if you're hankering to see some meteors, the total absence of moonlight makes 2009 an opportune year for the Orionids.
如果你非常渴望看到流星雨,月亮的缺席无疑让2009年成为观测猎户座流星雨最佳的年份。
