Orionid Meteor Shower 2025: How to See Halley's Comet Debris 2026

The Orionid meteor shower peaks this week, offering skywatchers a chance to see fragments of Halley's Comet streak across the night sky. The annual event occurs every October as Earth passes through a stream of dust left behind by the famous comet.

This year, the shower is expected to reach its peak during the night of October 21–22. Under ideal conditions, observers might see between 10 and 20 meteors per hour. However, a bright waxing gibbous Moon will interfere, drowning out many fainter meteors.

What Causes the Orionid Meteor Shower?

The Orionids are created by debris from Halley's Comet, which last passed through the inner solar system in 1986. As Earth crosses the comet's orbital path, tiny particles plunge into our atmosphere at about 66 kilometers per second.

These particles heat the surrounding air and produce the fleeting streaks of light we call meteors. The shower is named after the constellation Orion, as the meteors appear to radiate from a point near it.

When and Where to Watch

The peak occurs on the night of October 21–22, but conditions are not ideal due to the Moon. The Moon sets around 03:00 BST, leaving a few hours of darker sky before dawn.

At that time, Orion is climbing high in the sky, making it easier to spot meteors. Find a safe location with a wide view of the heavens and simply watch with the naked eye—no telescope needed.

Viewing Tips for the Orionids

• Best time: After moonset, in the early hours before dawn.
• Location: Away from city lights, with a clear view of the southeast.
• Equipment: None required—just your eyes and patience.
• Comfort: Bring a reclining chair or blanket to avoid neck strain.
• Patience: Allow 20–30 minutes for your eyes to adapt to the dark.

Challenges from the Moon

The waxing gibbous Moon will be bright on the peak night, washing out many fainter meteors. This reduces the number of visible streaks, especially before moonset.

However, the brighter meteors should still be visible, and the darker hours after moonset offer better chances. Patience and persistence are key.

Comparing Meteor Showers

Not all meteor showers are created equal. The table below compares the Orionids with other notable showers.

While the Orionids are less prolific than the Perseids or Geminids, they offer a unique connection to the most famous comet in history.

Why the Orionids Matter

Halley's Comet is perhaps the most famous comet, having been observed for millennia. The Orionids provide a yearly reminder of its passage and allow us to witness pieces of it burning up in our atmosphere.

For astronomers and enthusiasts alike, the shower is a chance to connect with a celestial visitor that won't return until 2061. Each meteor is a tiny fragment of that iconic comet.

What to Watch Next

If you miss the Orionids, don't worry—there are other celestial events to look forward to. The Perseid meteor shower in August is one of the most popular, and the Geminids in December offer a spectacular show.

Also, keep an eye out for fireballs, which are exceptionally bright meteors. For instance, a meteor sighting in New Zealand recently stunned sky watchers, highlighting the awe-inspiring nature of these events.

Before the Orionids, skywatchers in the UK were treated to a deep partial solar eclipse, which preceded the Perseid meteor shower. Such events remind us of the dynamic nature of our solar system.

Looking ahead, the fireball over New Zealand serves as a reminder that unexpected meteor events can occur anytime, so it's always worth glancing up.

And if you're planning a stargazing trip, consider timing it with the Perseid meteor shower, which often delivers a more impressive display. The background to this story is set out in Large Meteor Sightings in New Zealand Delight and Amaze. A related thread runs through Meteor Sightings in New Zealand: Fireballs Light Up Skies.

For now, focus on the Orionids and enjoy the show—even if the Moon tries to steal the spotlight. Earlier coverage in Celebrity: latest articles shows how the argument developed. A closer look at the same subject appears in Starwatch Guide: Tracking Down the Faint Stars of Pisces.
