Orionid Meteor Shower Peaks: How and When to Watch Halley’s Comet Debris Light Up the Sky

The Orionid meteor shower reaches its peak overnight on October 21–22, 2026, offering stargazers a view of fast-moving space debris left by Halley’s comet, WMUR reported.

When and where can you watch the Orionid meteor shower peak?

The meteor shower is active from October 2 to November 7, 2026, according to FOX9. The peak occurs on the evening of October 21 through the early morning of October 22, as reported by WMUR and The Weather Channel. CNN noted that the shower is predicted to peak officially at 2 p.m. ET on Wednesday, October 21, making the overnight hours between Wednesday and Thursday the ideal time to look up.

Sky-gazers in both the Northern and Southern Hemispheres can view the Orionids, weather permitting, according to FOX9. NASA advises observers in the Northern Hemisphere to lie flat on their backs with their feet facing southeast, while people in the Southern Hemisphere should face northeast under a clear night sky, FOX9 reported. The Weather Channel added that viewing hours run from midnight to dawn, and WMUR noted that best viewing may be between midnight and 2 a.m. ET, or after moonset, which is around 2:30 a.m. ET.

How many meteors will be visible per hour?

Weather permitting, observers can expect to see between 10 and 20 meteors per hour, according to FOX9 and CNYCentral. CNN reported that larger debris fragments can create exceptionally luminous fireballs as they break up in Earth’s atmosphere, and NASA noted that past showers have occasionally reached 60 to 70 meteors per hour.

The meteors travel at high speeds of 41 miles per second, or 66 kilometers per second, according to CNN. The Weather Channel stated that these fast-moving meteors leave behind a glowing train that can remain visible for seconds to minutes.

What role does Halley’s comet play in the October display?

The Orionids originate from dust and debris left behind by Halley’s comet, which crosses paths with Earth’s orbit every year in October, according to CNN. FOX9 reported that Halley’s comet takes approximately 76 years to complete one orbit around the sun. NASA stated that the comet was last visible from Earth in 1986 and will return in 2061.

CNN explained that Halley’s comet moves in a retrograde orbit, traveling in the opposite direction around the sun compared to Earth. The debris from the comet also creates a second annual meteor shower for Earth’s atmosphere every May, known as the Eta Aquarids.

How will regional weather and moonlight affect visibility?

Cloud cover and moonlight present mixed conditions for viewers across different regions. CNN reported that a waxing gibbous moon will be 76% illuminated on Wednesday night, just a few days before the full moon rises on October 26. While the bright moon may make it harder to spot meteors during parts of the viewing period, it is expected to set a few hours before sunrise, providing an optimal window for stargazers.

Regional weather patterns will also dictate visibility, according to The Weather Channel. Much of the central and eastern United States is forecast to have clear skies in the early morning hours on Thursday. However, thicker cloud cover could impact the Rockies, the Southwest, and parts of the West Coast including California, Oregon, and Washington. The Weather Channel also noted that a nor’easter brewing off the East Coast will bring thick clouds from New York City to New England, alongside rain and storms in the West.

How should stargazers prepare for the viewing experience?

Observers should find a spot away from light pollution and allow their eyes to adjust to the night sky, which usually takes about 15 to 20 minutes, according to WMUR, while NASA and The Weather Channel note that giving yourself 30 minutes in the dark helps your eyes adapt so the meteors become visible.
