Geminids Meteor Shower 2026 Viewing Guide: Dec 13–14 Peak and an Early-Setting Crescent Moon
Primary-source guide to the 2026 Geminids (active Dec 4–20, IMO peak Dec 14 at 14:00 UTC / 9:00 AM EST, ZHR 150): why Sunday night Dec 13 is the night to watch, the thin crescent Moon (about 25% lit by our DE440 calculation) that sets early, and asteroid 3200 Phaethon.
2026 Geminids Peak: December 13–14 and a Thin, Early-Setting Moon
A peak in the US morning. The IMO 2026 calendar lists the Geminids as active December 4 to 20. Their peak is December 14 at 14h UT, which is 9:00 AM EST (6:00 AM PST). [1]
A wide peak helps. The IMO says the shower "reaches its broad moon-free maximum on December 14 centred at 14h UT." It adds that Geminid rates stay at 100 or more for roughly 10 to 12 hours. In the past 20 years, peaks have all fallen in a window that, for 2026, runs from Dec 13 at 21h UT to Dec 14 at 18h UT (4:00 PM EST Dec 13 to 1:00 PM EST Dec 14). So the night of Dec 13–14 sits inside it. [1]
A thin Moon that leaves early. The IMO says there is "only a waxing crescent" at the peak. New Moon is on December 8 at 7:52 PM EST (Dec 9, 00:52 UTC). By our own calculation from JPL's DE440 ephemeris, the Moon is about 25% lit at the peak. Our DE440 calculation also puts moonset in New York at about 8:41 PM EST on December 13. [1] [4]
| Item | 2026 value | What it means for you |
|---|
| Active dates | Dec 4–20 (IMO); NASA lists Dec 4–17 | A few meteors each night for about two weeks |
| Peak (IMO) | Dec 14, 14:00 UTC (9:00 AM EST) | Watch Sun night Dec 13 into Mon morning Dec 14 |
| Ideal peak rate | ZHR 150 (IMO) | A best-case number for a perfect, dark sky |
| Real dark-sky rate | 40–50 per hour (NASA) | What a careful watcher can expect |
| Moon at peak | Waxing crescent (IMO); ~25% lit (our DE440 calculation) | Sets about 8:41 PM EST in New York (our DE440 calculation) |
| Radiant | RA 112°, Dec +33° in Gemini (IMO) | Rises near sunset; highest around 2 AM |
| Speed | 35 km/s, about 22 miles per second (IMO, NASA) | Medium-speed, often bright meteors |
Where the Geminids Come From: Asteroid 3200 Phaethon
Born from a rocky asteroid. Most meteor showers come from comets. NASA says the Geminids come from an asteroid, 3200 Phaethon. [2]
A small, odd object. NASA says Phaethon is about 5.10 km (3.17 miles) across. It circles the Sun once every 1.4 years. Scientists are not sure how to classify it. It may be a "dead comet" or a "rock comet." [2]
Denser bits. A 2010 study led by Jiří Borovička modeled how Geminid meteors brighten and slow down. It found typical densities of about 2.6 grams per cubic centimeter. That is much denser than bits that come from comets. [5]
How to Watch the Geminids on the Night of Dec 13–14, 2026
1. Start early. NASA notes that the Geminids are a good shower for young viewers because they start around 9 or 10 PM. The IMO says the radiant rises about sunset at northern latitudes and is highest near 2 AM local time. [1] [2]
2. Get away from lights. Find a dark spot away from city and street lights. Dress for winter, and bring a sleeping bag or lawn chair. [2]
3. Lie back and wait. Lie flat with your feet facing south and look up at as much sky as you can. Give your eyes about 30 minutes to adjust to the dark. Compare other showers in our Perseids, Geminids & Major Meteor Showers Guide and check dates on Eclipses, Meteor Showers & Sky Events. [2]
Frequently asked questions
When is the 2026 Geminid peak?
The IMO predicts it on Monday, December 14, 2026 at 14:00 UTC (9:00 AM EST). In North America, the best viewing night is Sunday night, Dec 13, into Monday morning, Dec 14.
How many Geminid meteors will I see in 2026?
The IMO lists an ideal peak rate of 150 per hour. NASA says to expect 40 to 50 per hour under dark skies.
Will the Moon get in the way of the 2026 Geminids?
Not much. The IMO says there is only a waxing crescent at the peak. By our DE440 calculation it is about 25% lit, and in New York it sets at about 8:41 PM EST on Dec 13.

★ 4.5/5
How to Kill an Asteroid: The Real Science of Planetary Defense
Robin George Andrews · ISBN 9781324131366
Science journalist Robin George Andrews goes inside NASA's DART mission. That intentionally crashed a spacecraft into an asteroid to change its orbit. Explains how astronomers hunt 'city-killer' space rocks and defend Earth.
Why this book matters to both sides
Explains how planetary radar tracks near-Earth asteroids and rules out impacts—essential reading for the 19,656-mile close pass of asteroid Apophis on Friday, April 13, 2029.

T. rex and the Crater of Doom
Walter Alvarez · ISBN 9780691169668
Geologist Walter Alvarez tells the true detective story of how a thin layer of cosmic iridium clay and the buried Chicxulub crater in Mexico proved that a giant asteroid wiped out the dinosaurs 66 million years ago.
Why this book matters to both sides
Shows both sides of how science tests a catastrophe claim: why geologists doubted cosmic impacts for decades. What hard physical proof finally changed their minds.

★ 4.5/5
The Cycle of Cosmic Catastrophes: How a Stone-Age Comet Changed the Course of World Culture
Richard Firestone, Allen West & Simon Warwick-Smith · ISBN 9781591430612
Written by members of the team that proposed the Younger Dryas comet impact. They argue that fragments of a giant comet exploded over North America 12,800 years ago, wiping out mammoths and triggering a 1,200-year cold snap.
Why this book matters to both sides
Gives the founding proponents' case for the 12,800-year-ago comet impact hypothesis, contrasting directly with both solar-outburst ideas and mainstream ocean-current models.
