Frequently Asked Questions

When is the next meteor shower?

The next meteor shower depends on today's date and your year selection. The calculator highlights the upcoming shower at the top of the results. Major annual showers occur every month, with the Perseids (August), Geminids (December), and Quadrantids (January) being the most prolific.

What is ZHR and what does it mean?

ZHR stands for Zenithal Hourly Rate — the number of meteors a single observer could see per hour under perfect dark-sky conditions with the radiant directly overhead. Real-world rates are often lower due to light pollution, horizon obstructions, and atmospheric conditions. A ZHR of 100+ is considered a major shower.

What time of night is best for watching meteor showers?

Most meteor showers are best observed after local midnight and before dawn, when your location on Earth rotates to face directly into the debris stream. The radiant point rises higher in the sky after midnight, increasing the number of visible meteors significantly.

How does the Moon affect meteor shower viewing?

A bright or near-full Moon washes out fainter meteors with its reflected light. Showers that peak near a new moon offer the darkest skies and the best views. Even a half-illuminated moon can reduce the number of visible meteors by 50% or more.

What causes meteor showers?

Meteor showers occur when Earth passes through trails of debris left behind by comets (and sometimes asteroids) as they orbit the Sun. The particles, called meteoroids, enter our atmosphere at speeds up to 70 km/s and burn up due to friction, creating the streaks of light we call meteors or shooting stars.

Are meteor showers visible from both hemispheres?

Most major showers are visible from both hemispheres, but showers with a radiant point near the northern celestial pole (like the Ursids or Quadrantids) favour northern observers. Showers like the Eta Aquarids are better seen from the Southern Hemisphere. This calculator notes the visibility advantage for each shower.

Which meteor shower produces the most meteors?

The Geminids (December) and Perseids (August) consistently produce the highest rates, with ZHRs of 120–150 under ideal conditions. The Quadrantids (January) can also spike to 120 ZHR, but the peak is very brief — only a few hours — making it easy to miss.

Do I need a telescope to watch meteor showers?

No — telescopes are actually a disadvantage for meteor watching because they have a very narrow field of view. Your naked eyes are the best tool. Find a dark location away from city lights, lie flat on your back, look up at a wide area of sky, and allow at least 20 minutes for your eyes to dark-adapt.
