How to Watch the Orionid Meteor Shower in October 2026 From Halley's Comet
Published:
In brief
The Orionid meteor shower, made of debris from Halley's Comet, peaks on the night of October 21–22, 2026, with NASA and the American Meteor Society forecasting 10 to 20 meteors per hour under dark skies. A bright, 74%-illuminated waxing gibbous moon will wash out fainter meteors, so the best views come in the few hours before dawn once the Moon has set.
Every October, Earth passes through a trail of dust left behind by Halley's Comet, producing the Orionid meteor shower. NASA explains that the Orionids 'are created by tiny pieces of debris left behind by Halley's Comet' as it swings through the inner solar system roughly every 76 years.
When the Orionids are active and when they peak
The American Meteor Society lists the shower as active from October 2 to November 7, 2026, with maximum activity on the night of October 21–22. The RASC Observer's Handbook, cited by EarthSky, pins the predicted peak more precisely at 18:00 UTC on October 21, and notes the shower has a broad, plateau-like maximum lasting several nights, so meteors can be seen on nights around the peak as well.
Why the Moon will interfere this year
Viewing conditions in 2026 are complicated by moonlight. The American Meteor Society reports a 74% illuminated waxing gibbous Moon on the peak night, and EarthSky notes the full Moon falls on October 25–26, just days after the Orionid maximum. NASA and EarthSky both point to a workaround: the Moon sets several hours before dawn on the peak mornings, opening a darker window in the hour before sunrise when fainter meteors become visible.
How to watch the Orionids, step by step
Mark the night of October 21 into the morning of October 22, 2026, as the main peak, but check skies on nearby nights too since the maximum is broad.
Plan to observe after the Moon sets and before dawn — NASA says this predawn window offers the darkest skies of the night.
Get away from city lights. Both NASA and EarthSky stress that light pollution is the biggest obstacle to seeing meteors, including the brighter streaks.
Give your eyes time to adapt to the dark before you start counting meteors — NASA advises skywatchers to let their eyes adjust before looking up.
Lie back or recline and watch a wide, open patch of sky rather than staring only at the constellation Orion, since meteors can streak across any part of the sky, not just near the radiant.
A telescope or binoculars are not required — the Orionids are visible to the unaided eye, though NASA notes binoculars or a telescope can reveal more detail in individual meteors for those who have them.

Where the dust comes from
Halley's Comet last passed through the inner solar system in 1986 and will not return until 2061, but it continuously sheds material along its orbit. EarthSky reports the comet's nucleus loses an estimated 1 to 3 meters (3 to 10 feet) of material on each passage, and Earth crosses this debris trail every October, producing the Orionids, and again in May, producing the related Eta Aquariid shower.
The radiant point — the spot in the sky the meteors appear to stream from — sits near what EarthSky describes as the upraised club of the constellation Orion the Hunter, which gives the shower its name. Brazilian outlet Metropoles also reported the October 2–November 7 active window and flagged the Moon's illumination, at roughly 70%, as the main challenge for spotting fainter meteors this year, consistent with the AMS figure.
Questions
When is the best night to watch the Orionids in 2026?
The peak is forecast for the night of October 21 into the morning of October 22, 2026, with maximum activity predicted around 18:00 UTC on October 21 according to the RASC Observer's Handbook cited by EarthSky. Because the maximum is broad, nearby nights can also produce meteors.
What causes the Orionid meteor shower?
The Orionids are created by debris that Halley's Comet has shed into its orbital path over many passages. Earth crosses this trail of dust and small particles every October, and the particles burn up in the atmosphere as meteors.
Will the Moon ruin the 2026 Orionids?
It will reduce visibility of fainter meteors: the American Meteor Society reports a 74% illuminated waxing gibbous Moon on the peak night, with the full Moon following on October 25–26. NASA and EarthSky both note the Moon sets several hours before dawn, leaving a darker predawn window for viewing.
How many meteors per hour can I expect to see?
Under dark skies away from the Moon's glare, the American Meteor Society and EarthSky cite typical rates of 10 to 20 meteors per hour, well below the 50–75 per hour seen in exceptional years such as 2006–2009.
Do I need a telescope to see the Orionids?
No. The shower is visible to the naked eye, which is NASA's standard guidance for meteor-shower viewing; NASA adds that binoculars or a telescope can reveal more detail in individual meteors for observers who want to use them.
How the world is telling it
PortugueseBrazilian outlet Metropoles covers October 2026 as a busy month for skywatching, tracking the month's lunar phases alongside the Orionids' October 2–November 7 active window. It highlights the Moon's roughly 70% illumination near the shower's peak as the main obstacle to seeing fainter meteors and advises readers to seek locations away from city light pollution.

Satellites stay in orbit because their forward speed balances Earth's gravity, and the altitude chosen determines what job a satellite can do. Low orbits give sharp images and short delays, geostationary orbits give constant coverage of one region, and medium orbits power global navigation — each linked to ground stations by radio signals regulated through an international frequency system.
Space telescopes orbit above Earth's atmosphere, which blocks or distorts most infrared, ultraviolet and X-ray light before it reaches the ground. By operating outside that barrier, observatories such as Hubble, Webb, Gaia and Chandra each capture a different slice of the electromagnetic spectrum, and together they build a more complete picture of stars, galaxies and the early universe.
Meteor showers are best seen with the naked eye, from a dark location, in the hours between midnight and dawn when a shower's radiant climbs highest in the sky. Checking the Moon phase, letting your eyes adapt to the dark, and looking slightly away from the radiant are the steps experts most often repeat.
Beginners can start observing the night sky with no equipment at all: let your eyes adjust to darkness for at least 15-20 minutes, learn to tell planets from stars by their steady (non-twinkling) light, and use a star chart or app before buying any gear. Binoculars, not a telescope, are the recommended first upgrade, according to NASA and EarthSky.
