The Orionid meteor shower 2024: How to watch

When does the Orionid meteor shower peak?

The 2024 Orionid meteor shower peaks on the night between October 20 and October 21. The Orionids can produce bright, fast meteors that make for a spectacular show with the constellation Orion in the background.

From a dark sky location, you can expect to see an average of about 20 meteors per hour during the shower's peak activity, though on rare occasions the Orionids can display 50-75 meteors per hour. The meteor shower should be visible in both the Northern and Southern Hemisphere.

There will be an almost-full Moon in the night sky during the peak of the 2024 Orionids, which mill make the shower significantly more difficult to view. The shower will also be present, though less active, during the few weeks before and after peak. 

What causes the Orionid meteor shower?

The Orionid meteor shower is caused by debris from Halley's Comet, also known as comet 1P/Halley. The comet's 76-year orbit brings it close enough to Earth to have been seen in the night skies for centuries. It last passed close to Earth in 1986 and will return in 2061.

Where can I watch the Orionid meteor shower?

The Orionids are visible to skywatchers in both the Northern and Southern Hemispheres. Meteors will appear to come from the area of the constellation Orion, which rises in the east in the hours after midnight during October. Meteors will streak out from this area in all directions.

The best way to watch a meteor shower is from a dark sky site, so it helps to get away from city lights as much as you can. Skywatchers should go to the darkest place they can, let their eyes adjust, and look overhead — but avoid staring directly at the Moon.

What is a meteor? 

Meteors are also known as shooting stars, but they aren't actually stars at all. Meteors are streaks of light in the sky caused by dust and small rocks burning up as they hit Earth's atmosphere at very high speeds — tens of kilometers per second.

These small particles create bright streaks of light you can see from the ground at night. In general, the bigger the piece of space dust, the brighter the meteor.

Space is full of dust, so on a typical night from a dark location, you might see up to 10 meteors per hour — no shower required!

What is a meteor shower?

Meteor showers occur when the Earth passes through debris shed by a comet or asteroid. They reoccur at about the same time every year, when Earth comes around in its orbit and passes through the debris again.

Two of the best meteor showers of the year are the Perseids, which peak in mid-August, and the Geminids, which peak in mid-December. The Perseids often get more media attention because they occur during the northern hemisphere summer. However, the Geminids typically produce more meteors.

Meteor showers are named after the constellation that contains the radiant of the shower. The radiant is where the meteors appear to emanate from — if you draw a line back along the meteors, all of the lines will meet at the same point. This is an effect of the Earth speeding through the comet debris, meaning when you watch a meteor shower, you're seeing direct evidence of our planet orbiting the Sun!

How to watch a meteor shower

All you need to watch a meteor shower is your eyes, patience, and a mostly cloud-free night. Go out, get comfortable, and stare at the sky. Typically the best view of a meteor shower comes between midnight and pre-dawn hours, because that's when you are on the leading side of the Earth, watching the comet debris come at you like rain hitting a car windshield.

You don’t have to stargaze in the direction of the radiant; in fact, meteors farther away from it will appear longer. It is often said that an ideal place to look is 45 degrees away from the radiant, but the most important factor is getting to a dark location away from light pollution, letting your eyes adjust for several minutes, and looking at the darkest patch of sky you can.

Go out, look up at the night sky and have fun!
