Earth plunges into Halley’s Comet debris overnight on October 21-22, 2026, delivering the annual Orionid meteor shower. Stargazers can spot 10 to 20 shooting stars per hour during pre-dawn hours, though a bright waxing gibbous Moon will wash out fainter streaks until it sets.
October 21-22, 2026 Peak and Comet 1P/Halley Orbital Debris
The annual Orionid meteor shower reaches its maximum intensity overnight on October 21-22, 2026, as Earth crosses the dusty trail shed by Comet 1P/Halley. The particles collide with our planet’s atmosphere at roughly 41 miles or 66 kilometers per second, vaporizing into fleeting streaks of light.
While the comet itself last visited the inner solar system in 1986 and is not expected to return until 2061, its orbital debris leaves a reliable, fast-moving display each autumn. Active from October 2 through November 7, the shower peaks when Earth encounters the densest portion of the stream.
The high velocity of the Orionids is driven by the fact that their parent body, Halley’s Comet, revolves around the sun in a retrograde direction opposite to the planets.
Moonlight Glare and the Pre-Dawn Window for Orionid Viewing.
The lunar glare washes out fainter meteors for much of the night, making precise timing essential for observers hoping to catch the display.
Conditions improve significantly during the early morning hours once the lunar disk sets.
Orionid meteors are best spotted between the hours of midnight and dawn on Oct. 22, when 10-20 shooting stars may be seen brightening the night sky each hour under ideal dark-sky.
Space
Even if unfavorable weather or cloud cover spoils the view on the primary peak nights, observers can still catch activity during the mornings immediately preceding and following the maximum.
Locating the Radiant Near Betelgeuse in Orion.
Stargazers looking to trace the paths of the meteors should direct their gaze toward the constellation Orion. The shower’s radiant — the vanishing point from which the parallel paths appear to originate — sits close to the red giant star Betelgeuse in the Hunter’s upraised club.
Observing directly at the radiant is discouraged. Experienced stargazers recommend looking 40 to 90 degrees away from Orion to catch meteors at their longest trajectories, where glowing trains linger in the wake of the fast-moving particles.

Historical Discovery and Viewing Strategies.
Edward C. Herrick, Adolphe Quetelet, and Johann Benzenberg Discoveries in the 1830s
Western astronomers were not aware of the meteor shower until the 1830s. American amateur scientist Edward C. Herrick drew attention to a potential new shower after observing a substantial increase in meteor counts in mid-October 1839 and again in 1840. Simultaneously, astronomers Adolphe Quetelet and Johann Benzenberg documented comparable activity around that same period, earning recognition as independent co-discoverers.
