The annual Orionid meteor shower, which originates from Halley’s Comet, is now lighting up the night sky, offering a spectacular celestial show. This highly anticipated event occurs every October when Earth passes through the debris trail left by Halley’s Comet. While the comet itself won’t return until 2061, its fragments put on a dazzling display for stargazers worldwide.
The meteor shower officially began on September 26, 2024, but it will peak between October 20 and 22, when skywatchers can expect to see the highest concentration of meteors streaking across the heavens.
What Is the Orionid Meteor Shower?
The Orionid meteor shower gets its name from the constellation Orion, from which the meteors appear to radiate. The meteor shower consists of debris left behind by Halley’s Comet, which completes an orbit around the Sun every 75 to 76 years. Each year, Earth passes through the comet’s debris trail, and particles enter our atmosphere at speeds of up to 66 kilometres per second. When these particles collide with our atmosphere, they create bright streaks of light known as shooting stars.
Halley’s Comet is the source of two major meteor showers: the Eta Aquarids in May and the Orionids in October. While the Eta Aquarids are more visible in the Southern Hemisphere, the Orionids offer better views in the Northern Hemisphere.
Peak Viewing Dates and Times
For the best chance to catch the Orionid meteor shower at its peak, mark your calendar for October 20-22, 2024. During this period, observers can expect to see between 20 and 30 meteors per hour in ideal conditions. While the shower is active from late September to early November, the peak nights will provide the most stunning displays, with the highest number of meteors visible in the pre-dawn hours.
If you’re hoping to capture the best view, find a location far from city lights to reduce light pollution. Additionally, make sure to give your eyes at least 20 minutes to adjust to the darkness. No special equipment is needed—just a clear sky and a little patience.
Global Viewing Conditions
This year’s Orionid meteor shower is visible in both the Northern and Southern Hemispheres, but the best viewing conditions are in the Northern Hemisphere. Those living in rural areas with minimal light pollution will have the best chances of witnessing the meteors. While the full Moon, which occurs on October 17, may slightly hinder visibility in the days leading up to the peak, the shower’s brightest meteors should still be easily visible.
For the optimal experience, experts recommend looking towards the eastern sky after midnight and into the early morning hours. The meteors will appear to originate from the Orion constellation, near the star Betelgeuse.
Looking Forward to 2061
While Halley’s Comet itself won’t return to our skies until 2061, the annual Orionid and Eta Aquarid meteor showers continue to provide a connection to this legendary comet. Each streak of light you see is a small piece of history, a fragment of a comet that has been visible to humanity for thousands of years.
With clear skies and the right timing, this year’s Orionid meteor shower promises to be a breathtaking experience for skywatchers. Don’t miss your chance to see one of the most beautiful meteor showers of the year!
