Orionid Meteor Shower Peaks in Time for Halloween, Offering Streaking Meteors Across Night Sky

The Orionid meteor shower, produced by the remnants of Halley's Comet, is forecast to reach its peak in a matter of days, sending a flurry of bright and fast meteors across the night sky. According to NASA, the meteors, which whizz at about 148,000 mph into Earth's atmosphere, will leave glowing trains of debris in their wake that can last for several seconds or even multiple minutes. However, spectators eager to catch a glimpse of the spectacle will have to contend with a bright moon outshining the meteors and rely on clear evening skies.

Key Takeaways:

• The Orionid meteor shower is active from September 26 to November 22, with the peak activity expected to occur on Sunday and Monday.
• The best opportunity to witness streaking meteors is from midnight to dawn on those days, with experts recommending a clear evening sky and minimal moonlight.
• The shower produces an average of 10 to 20 meteors per hour at its peak, although the numbers can be higher, such as 50 to 75 meteors per hour in exceptional years like 2006-2009.
• Spectators can see up to 23 meteors per hour blazing across moonless skies at 41 miles per second in both the Northern and Southern Hemispheres, according to NASA.
• The meteors are visible anywhere in the night sky, particularly 45 to 90 degrees away from the radiant, and are named after the constellation Orion because they seem to emerge from the same area in the sky.
• The Orionid meteor shower is caused by Earth passing through dusty debris trails left by Halley's Comet, with the meteoroids colliding with Earth's atmosphere at high speed and disintegrating to create the fiery and colorful streaks in the sky.

Statistics:

• Average number of meteors per hour at peak activity: 10-20
• Exceptional year meteors per hour: 50-75
• Speed of meteors: 41 miles per second
• Peak activity dates: Sunday and Monday
• Active period: September 26 to November 22
• Speed of meteors entering Earth's atmosphere: 148,000 mph
