The Meteor Shower That Once Stopped the World
In November 1833, people across North America woke to what many described as the sky falling. An estimated 100,000 meteors per hour rained down over several hours — a storm so intense that some witnesses dropped to their knees in prayer. Newspapers called it the end of times. Scientists called it a revelation. That event permanently cemented the Leonid meteor shower in the history books, and every year in mid-November, Earth returns to the scene of the crime.
The 2026 Leonids peak on the night of November 17–18, and while we're almost certainly not in for a repeat of 1833's legendary storm, the shower is still one of autumn's most rewarding astronomical events — and one of the fastest you'll ever witness.
Why the Leonids Are So Extraordinarily Fast
Not all meteor showers are created equal. The Leonids hold a unique distinction: they are the fastest meteors observable from Earth, entering our atmosphere at roughly 71 kilometres per second (about 158,000 mph). To put that in perspective, the Perseids — the beloved August shower — hit at around 59 km/s, and even they feel blindingly quick.
This blistering speed is a consequence of geometry. Earth and the Leonid debris stream are essentially travelling toward each other in almost head-on trajectories, maximising the relative velocity. The result is meteors that leave long, glowing trains across the sky — sometimes lingering for several seconds after the meteor itself has gone. These persistent trains, twisting slowly in high-altitude winds, are one of the Leonids' most photogenic signatures.

Comet Tempel-Tuttle: The Culprit Behind the Show
Every meteor shower has a parent comet, and the Leonids' is Comet 55P/Tempel-Tuttle, a roughly 3.6-kilometre-wide chunk of ice and rock that orbits the Sun every 33 years. As the comet travels through the inner solar system, solar heat boils off its surface, releasing a river of dust and gravel that spreads out along its orbital path over millennia.
Each November, Earth crosses this debris highway. Individual particles — most no larger than a grain of sand or a small pebble — vaporise violently in our upper atmosphere, producing the streaks of light we see from the ground.
The legendary storms, like 1833 and again in 1966 (when rates briefly hit an astonishing 40–150 meteors per second over the American southwest), occur when Earth passes through particularly dense clumps of debris shed during recent perihelion passages of the comet. Tempel-Tuttle last swung through the inner solar system in 1998, which is why the late 1990s and early 2000s produced elevated — though not storm-level — Leonid displays.
What to Expect in 2026
For 2026, forecasters anticipate a moderate but worthwhile display, with rates of roughly 10–20 meteors per hour under dark skies. That's not a storm, but it's enough to make a late-night session very satisfying — especially given the quality of each meteor. The radiant rises in the east after midnight local time, so the best observing window is roughly 1:00 AM to dawn on November 18.
A few practical tips:
- Check the Moon phase first. A bright Moon is the meteor-watcher's biggest enemy. Use the Moon Phases calendar to confirm how much moonlight you'll be dealing with on peak night — the waning crescent in late November 2026 should cause only minimal interference.
- Find genuinely dark skies. Even 30–40 minutes outside a city can dramatically improve your count. Use ChronoKit's Sunrise & Sunset times to know exactly when astronomical darkness begins in your location.
- Dress warmer than you think you need to. November nights are unforgiving. Lying still on a reclining chair for an hour in cold air is a different experience from walking around.
- Give your eyes 20 minutes to dark-adapt. No phones, no torch. Just patience — it pays off.
- Don't stare at the radiant. Look about 40–50 degrees away from Leo. Meteors will appear longer and more dramatic the further from the radiant you focus.
The Storms Will Return — Eventually
One of the most exciting things about the Leonids is the possibility of a future storm. Astronomers calculate that the next realistic opportunity for an elevated display may come in the 2030s, as Earth encounters filaments of debris associated with Tempel-Tuttle's 1965 and 1998 passages. No guarantees — meteor forecasting is notoriously tricky — but the prospect alone makes every November Leonid session feel like a scouting trip for something potentially historic.
For now, mark your calendar for the night of November 17–18, wrap up warm, and look east after midnight. The fastest shooting stars of the year are coming.
