The Orionid Meteor Shower peaks in late October, though Orion Meteors can be seen for roughly one week. Most years this shower produces 15-20 meteors per hour at it peak. However, in 2011, the count was much higher. The Orionids, as its name suggests, radiants out of the constellation of Orion - between Orion and Gemini, and is the most prolific meteor shower associated with Halley's Comet.
