A familiar name from space history will be connected to an October skywatching event, not because the comet itself is returning, but because Earth will pass through debris left behind by it. 

The annual Orionid meteor shower is expected to be active from Oct. 2 through Nov. 7, 2026, with the peak arriving on the night of Oct. 21–22. The display happens when Earth crosses a trail of dust and rocky material released by 1P/Halley, commonly known as Halley’s Comet. As these tiny particles enter Earth’s atmosphere, they create the streaks of light known as meteors. 

The event gives skywatchers a chance to see the effects of a famous comet without the comet itself appearing overhead. Halley’s Comet will not be visible during this October event, and it is not returning this year. The meteors come from older debris grains the comet shed during earlier journeys through the inner solar system.  

When to Watch the Orionids

The best opportunity to see the Orionids is expected around the peak night of Oct. 21–22. For viewers, the strongest viewing period is generally after midnight through pre-dawn on Oct. 22, weather permitting. 

Under genuinely dark skies, observers may see about 10–20 Orionids an hour near the peak. That number is a favorable-conditions estimate, not a promise for every viewer, as local conditions can affect how many meteors are visible. 

The Moon may make this year’s viewing more challenging. During the Oct. 21–22 peak, a 74% illuminated waxing-gibbous Moon is expected, and the extra light can hide some of the fainter meteors.  

Where to Look in the Sky 

The Orionid meteor shower gets its name from the constellation Orion because its radiant, the area where the meteors appear to begin, is near Orion, just north of Betelgeuse. 

However, viewers should not focus only on Orion. Meteors can appear anywhere across the sky, and NASA recommends watching a broad area about 45–90 degrees away from the radiant rather than staring directly at the source point.
