Generate a random meteor shower, from headline summer events to quieter seasonal showers, for planning a viewing night or learning something new about the night sky.
A meteor shower occurs when Earth crosses the debris trail left by a comet and the grains burn up around 70 to 120 kilometres overhead. Because the debris travels on parallel paths, perspective makes the meteors appear to radiate from a single point, and that radiant gives each shower its name: Perseids from Perseus, Leonids from Leo. Showers recur on the same dates annually, since Earth meets the same trail at the same point in its orbit. Most of the particles are smaller than a grain of sand, and the light comes from air compressing ahead of them, not from the grain itself burning.
This generator draws from a curated list of real, recognized annual meteor showers across four seasonal categories -- Winter Showers, Spring Showers, Summer Showers, and Autumn Showers -- from headline events like the Perseids and Geminids to quieter showers most stargazers have never heard of.
Every result here is drawn using crypto.getRandomValues() -- the Web Crypto API's cryptographically secure randomness -- instead of Math.random(), so it's genuinely unpredictable, not just statistically random. Learn more.
Stargazers and astronomy hobbyists use it to pick a shower to plan a viewing night around, or to learn its parent comet, peak date, and typical rate. Writers, teachers, and trivia hosts use it to surface an interesting fact for a lesson or a game. It's also a quick way to discover lesser-known showers beyond the handful that make the news every year.
Generate draws one meteor shower at random from the full pool using the site's cryptographically secure randomness, guaranteed not to repeat whatever result is currently showing in single-result mode. Filtering by season narrows the pool before drawing, and each single result comes with a short description of the shower's parent body, peak timing, and a notable fact alongside its name.
A sample of what this generator can draw, spread evenly across the full list:
All of them are real, recognized annual meteor showers, including their descriptions -- nothing here is invented.
Yes -- use the filter button to pick one or more of the four seasons. Generate will then only draw from showers in the seasons you've selected.
Not in single-result mode -- each new roll is guaranteed to differ from the one currently on screen.
Yes -- well-known showers like the Perseids, Geminids, and Leonids are in the pool alongside quieter, less familiar ones.
