Leonid Meteor Shower 2023: Peak Viewing Guide and What to Expect
Stargazers are in for a treat this week as the annual Leonid meteor shower reaches its peak. Experts predict enhanced activity overnight tonight, November 18th, offering a spectacular celestial display. While a nearly full moon will present some challenges, patient observers could still witness up to 10-20 meteors per hour, streaking across the night sky. This year’s Leonids promise a captivating show for those willing to venture out and look up.
What are the Leonids?
The Leonid meteor shower occurs every year as Earth passes through debris left behind by comet Tempel-Tuttle. These tiny particles, mostly dust and ice, burn up in Earth’s atmosphere, creating the bright streaks of light we know as meteors, or “shooting stars.” The Leonids are known for their fast-moving meteors and occasional outbursts of intense activity. Astronomy Magazine provides a detailed look at tonight’s sky conditions.
When and Where to Watch the Peak
The peak of the Leonid meteor shower is expected between midnight and dawn on November 18th and 19th. To maximize your viewing experience, find a location away from city lights, with an unobstructed view of the sky. Allow your eyes at least 20-30 minutes to adjust to the darkness. The meteors will appear to radiate from the constellation Leo, hence the name “Leonids,” but they can appear anywhere in the sky. CNN offers a comprehensive guide on how and when to view the peak.
Tips for Optimal Viewing
While the nearly full moon will wash out some of the fainter meteors, there are still steps you can take to improve your chances of seeing a spectacular show. Dress warmly in layers, as November nights can be quite cold. Bring a comfortable chair or blanket to lie on. Avoid looking directly at the moon, as it will reduce your night vision. Instead, focus on the darker areas of the sky. Binoculars or a telescope are not necessary, as they restrict your field of view. The New York Times details how to best prepare for watching the Leonids.
The Science Behind Meteor Showers
Meteor showers are a regular occurrence, resulting from Earth’s orbit intersecting with the trails of debris left by comets. As a comet travels through the solar system, it sheds particles due to the sun’s heat and gravitational forces. These particles spread out along the comet’s orbit, forming a stream of debris. When Earth passes through these streams, the particles enter our atmosphere at high speeds, creating the dazzling display of meteors. The Leonids, in particular, are associated with comet Tempel-Tuttle, which has an orbital period of 33 years.
The speed at which these meteors enter the atmosphere is also a key factor in their brightness. Leonid meteors are known for their high entry speeds, often exceeding 70 kilometers per second. This high speed generates intense friction with the atmosphere, causing the particles to burn up brightly. Did you know that the color of a meteor can reveal its composition?
Beyond their visual spectacle, meteor showers provide valuable insights into the composition of comets and the early solar system. By studying the debris trails, scientists can learn more about the materials that formed our planets and the conditions that existed billions of years ago. Space.com offers further in-depth information on the science of meteor showers.

Frequently Asked Questions About the Leonid Meteor Shower
What is the best time to see the Leonid meteor shower?
The best time to view the Leonid meteor shower is typically between midnight and dawn, when the radiant point (Leo) is highest in the sky.
Will the moon affect the Leonid meteor shower visibility?
Yes, the nearly full moon will create some light pollution, potentially washing out fainter meteors. However, brighter meteors should still be visible.
Do I need any special equipment to watch the Leonid meteor shower?
No, you don’t need any special equipment. Your eyes are the best tool! Just find a dark location and allow them to adjust to the darkness.
What causes the Leonid meteor shower?
The Leonid meteor shower is caused by Earth passing through debris left behind by comet Tempel-Tuttle.
How often does the Leonid meteor shower occur?
The Leonid meteor shower occurs annually in November, but the intensity varies from year to year. Peak activity typically occurs every 33 years when Earth passes through a denser region of debris.
Is the Leonid meteor shower visible from all locations?
The Leonid meteor shower is visible from most locations on Earth, but the best viewing is generally from the Northern Hemisphere.
