Geminids 2027
The strongest annual shower — slow, bright, often colorful meteors all night long.
Viewing conditions this year
The Moon will be 99% illuminated on the peak night — poor — bright moon washes out faint meteors. Bright moonlight will hide most meteors this year; only the brightest will be visible. Worth a look if you're already outside, but temper expectations — and note next year's geometry may be far better.
What causes a meteor shower?
Comets (and a few asteroids) shed streams of dust along their orbits. When Earth crosses one of those streams — the same dates every year — the particles hit our atmosphere in parallel, appearing to radiate from one point in the sky. Each visible meteor is typically a fragment the size of a sand grain, vaporizing 80–100 km overhead.
How to actually see meteors
No telescope — your eyes have the widest field of view. Get away from city lights, give your eyes 20–30 minutes to dark-adapt (no phone screens), lie back, and watch as much sky as possible. Rates are almost always best after midnight, when your side of Earth faces into the stream. The quoted ZHR (zenithal hourly rate) is a perfect-conditions ceiling; expect to see a third to half of it under a good dark sky, less with moonlight.
Where it comes from
Geminids meteors are debris shed by (3200) Phaethon. They appear to radiate from the constellation Gemini, and the shower is best seen from both hemispheres. Rates build over the active window (Dec 4 – Dec 20) and drop quickly after the peak.
