The Orionid meteor shower is one of the best known and most reliable meteor showers in the annual calendar, visible from across the globe.
In 2024 the Orionid meteor shower is active from 2 October - 7 November and will peak on the night of 21-22 October between midnight and dawn. However, you should be able to see the shower for several days on either side of this 'maximum' date.
What is the Orionid meteor shower?
Some people view the Orionids as extra special as the meteors are actually pieces of Comet 1P/Halley, famously known as Halley's Comet. 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 is the Orionid meteor shower?
The Orionids occur in late October each year with a peak around the 21st. 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.

How can I watch the Orionid meteor shower?
Hunting for meteors, like the rest of astronomy, is a waiting game, so it's best to bring a comfy chair to sit on and to wrap up warm as you could be outside for a while. They can be seen with the naked eye so there's no need for binoculars or a telescope, though you will need to allow your eyes to adjust to the dark.
In 2024 the Moon will be waning gibbous, so conditions are not particularly favourable this year.
However, the shower lasts for over a month, so if the Moon affects the peak you may still be able to catch a few meteors throughout the shower's duration.
Where is best to watch the Orionid meteor shower?
For the best conditions, you want to find a safe location away from street lights and other sources of light pollution.
The meteors can be seen in all parts of the sky, so it’s good to be in a wide open space where you can scan the night sky with your eyes. But if you trace the paths that the meteors take, they seem to originate from the constellation of Orion.
If you manage to get any pictures of the Orionid meteor shower then we'd love to see them. You can find us on Facebook or Twitter.

Orionid meteor shower facts
- If you trace the path that the Orionid meteors take, they seem to originate from a point in the constellation of Orion - hence the name.
- The beautiful streaks we see in the night sky can actually be caused by particles as small as a grain of sand!
- The cometary debris enters our planet’s atmosphere at speeds of around 41 miles per second.
