One of the “best known and most reliable” meteor showers in the astronomical calendar will peak tonight (Monday, October 21). The Orionid meteor shower, active from October 2 until November 7 is set to be visible across UK skies. Orionids are often described as “extra special” as the meteors are pieces of Comet 1P/Halley, famously known as Halley's Comet.
Royal Museums Greenwich adds: “The comet swings by the earth only once every 75 - 76 years but this annual shower provides some compensation for those who may miss that once-in-a-lifetime event. “As the comet follows its path around the sun, it leaves a path of tiny debris. The cometary debris enters our planet’s atmosphere at speeds of around 41 miles per second, vaporising from friction with the air causing the streaks of light we call meteors.
” When does the Orionid meteor shower peak in 2024? The Orionids occur in late October each year and peak on October 21-22 (Monday night into Tuesday). “Although the Orionid maximum is quoted as 21-22 October in 2024, in fact there is a broad maximum lasting about a week roughly centered on that date,” explains Royal Museums Greenwich. The experts say stargazers should be able to see the meteor shower for “several days on either side of this 'maximum' date'.
" @starwalkapp Get ready to see the Orionids peak on October 22. 🌠 The meteor shower will produce up to 20 meteors per hour. It's the best meteor shower you'll witness in October and November, so make sure.
