Annual Probability of Seeing a Major Meteor Shower

Several major meteor showers occur each year with predictable schedules, and under good viewing conditions, about 30% of Americans witness at least one. The most prominent annual meteor showers include the Perseids (mid-August, 50-100 meteors per hour at peak), Geminids (mid-December, 120-150 per hour, the most prolific), Leonids (mid-November, typically 10-15 per hour but occasionally producing meteor storms), and Quadrantids (early January, 60-120 per hour but with a short peak).

Viewing success depends heavily on light pollution, weather, moon phase, and geographic location. Only about 20% of Americans live in areas dark enough to see the Milky Way, and light pollution affects meteor shower visibility proportionally. The best viewing typically occurs after midnight, away from city lights, during a new moon phase.

A "falling star" or meteor is typically a particle ranging from a grain of sand to a small pebble burning up in Earth's atmosphere at speeds of 25,000-160,000 mph. Meteor showers occur when Earth passes through debris trails left by comets. On any given night (even outside shower periods), about 5-10 random meteors per hour can be seen under dark skies. International Dark-Sky Association-designated dark sky parks offer the best viewing opportunities.
