The Orionid meteor shower is notable as the second meteor shower of the year produced by Earth passing through debris left behind by Comet 1P/Halley (aka Halley's Comet).
Although the Orionids do not approach the number of meteors produced by the August Perseids, skywatchers can still see up to around 20 meteors every hour under a clear, dark sky.
The best time to watch this shower will be after midnight, once the first-quarter moon has set in the west.
