The Geminids: a December night in London
· all times GMT
After the Moon sets, a long dark stretch opens over London. Earth crosses the dusty trail of asteroid 3200 Phaethon, and the Geminids appear to stream from Gemini as it climbs in the south.

This is a fixed London example. The map shows Gemini and nearby stars, not meteors.
When should I go out?
For London, try from about 22:00 GMT on 13 December into the early hours of the 14th. The Moon has set, the sky is dark, and Gemini is rising well above the eastern horizon. Near 02:00, its radiant stands about 71° high in the south; that is a direction cue, not a spot to stare at.
- About 20:00 GMT on 13 December: the Moon sets; Gemini’s radiant is about 25° high.
- About 22:00: a practical time to begin watching, once darkness has settled.
- About 02:00 GMT on 14 December: the radiant is about 71° high, toward the south.
- About 05:55: astronomical dawn begins as the Sun rises to 18° below the horizon.
Calculated for central London. The highlighted stretch is a useful observing window, separate from the shower’s predicted broad maximum on 13–14 December.
Why do the trails seem to start in Gemini?
It is perspective. Snowflakes seem to rush from one point when you travel through them; parallel railway lines appear to meet in the distance. Geminid meteors are small pieces of material entering Earth’s atmosphere, but their paths seem to spread from one patch of sky. Astronomers call that patch the radiant, and for this shower it lies among the stars of Gemini.
The constellation is a guide to the shower’s name, not the source of the meteors. That source is 3200 Phaethon, an unusual rocky body whose dusty trail Earth crosses each December. NASA describes the Geminids as one of the year’s strongest showers. Its 40–50 per hour figure is for observed rates under dark skies; a perfect-conditions theoretical rate is higher. Neither is a promise for a London street or a particular observer. Buildings, cloud, haze and nearby lights change what reaches your eyes.
The peak is broad, not a single guaranteed minute. The American Meteor Society lists the 2026 maximum across the night of 13–14 December and notes that Gemini is well placed from around 22:00. Moonlight is limited this year: for central London the Moon sets close to 20:00 on the 13th, leaving the later hours moon-free.
A few minutes outside
You do not need a telescope or binoculars. Give your eyes about 20–30 minutes to adapt to the dark, keep bright phone screens away, and look across a wide patch of sky roughly halfway up. The radiant helps identify a Geminid after you spot a streak; looking straight at it gives you a narrower view.
For the London example at 02:00 GMT on 14 December, Gemini is high toward the south. The map link opens that moment and selects Gemini so you can recognise the surrounding stars. It does not draw a radiant, predict meteor paths, or know your cloud and light-pollution conditions.
