The Geminids, the second-to-last meteor shower of the year, are expected to hit peak activity tomorrow night, Dec. 13, into the morning of Dec. 14. Reno's forecast is expected to be clear, providing an unobstructed view of what is considered one of the best meteor showers of the year.
That's because, among professional and amateur astronomers alike, the Geminids are considered to be the cream of the crop. The cosmic display is famed for its strong, bright and colorful fireballs that blaze across the sky at speeds reaching about 21 miles per second.
While a waning crescent moon could interfere with the shower's visibility in 2025, you should still have good chances of catching the whizzing meteors when the Geminids peak.
Whether Renoites want to see if they can peek out their windows at the upcoming astronomical event or if they want to travel to visit one of Nevada's DarkSky locations, here's everything Northern Nevadans need to know about the Geminid meteor shower, how to view it and what astronomical events are coming up before the end of 2025.
When is the Geminid meteor shower?
The Geminid meteor shower became active Dec. 4 and is expected to remain so until at least Dec. 17, according to the American Meteor Society.

Geminid meteor shower 2025: When to watch for peak activity
In 2025, the Geminid meteor shower is set to peak between Saturday, Dec. 13, and Sunday, Dec. 14, according to the Planetary Society.
The best time to see meteors is typically between midnight and pre-dawn hours. However, the Geminids are considered to be one of the best opportunities for young stargazers since the shower can start as early as 9 p.m. locally, according to NASA.

How many meteors will be visible? What to know about shower rate
When the Geminids are most active, stargazers have the opportunity to witness a dizzying 120 meteors per hour under the right weather conditions.
But it’s not just the quantity of meteors that makes the Geminids famous, but also their quality. The meteors produced by the Geminids' parent asteroid have a reputation for being colorful, sometimes appearing as yellowish streaks.
While it is now one of the year's strongest meteor showers, the Geminids didn't start out that way, according to NASA. When the shower first began appearing in the mid-1800s, only 10 to 20 meteors could be seen per hour.
Could the moon interfere with Geminids?
In 2025, the moon will be 30% full and in a waning crescent phase during the peak of the Geminid meteor shower. The moon will rise by 2 a.m. local time, after which spectators can still have success spotting meteors by facing west to keep the moon and its light at their backs, according to the American Meteor Society.
How to watch Geminids: Tips for seeing streaking meteors
The Geminids are named after the constellation Gemini because the meteors seem to emerge – or radiate – from the same area in the sky.
But astronomers caution that the radiant is not a good guide for where stargazers should look to view the zipping meteors, which should be visible across the night sky around the globe.
Here are some general viewing tips from NASA:
It should take less than 30 minutes for your eyes to adapt so that you can see streaking meteors.
Want to find a dark area near you? DarkSky International is a U.S. nonprofit that maintains a list of designated dark sky communities around the world, including 166 in the United States.
There are two DarkSky locations in Nevada: one in Great Basin National Park and one at the Massacre Rim Wildlife Study Area.
Can you see the meteor shower in Nevada?
The National Weather Service forecast for Reno calls for clear skies during the peak Saturday night, Dec. 13, providing an unobstructed view of the Geminids.
What causes the Geminids? Are meteor showers 'shooting stars?'
Meteor showers occur when Earth passes through dusty debris trails left by comets and other space objects as they orbit the sun.
The debris – space rocks known as meteoroids – collides with Earth's atmosphere at high speed and disintegrates, creating fiery and colorful streaks in the sky, according to NASA.
Those resulting fireballs, better known as "shooting stars," are meteors. If meteoroids survive their trip to Earth without burning up in the atmosphere, they are called meteorites, NASA says.
Unlike most meteor showers, the Geminid meteor shower doesn't originate from a comet, but from an asteroid.
Astronomers theorize that the asteroid, 3200 Phaethon, could be what’s known as a “dead comet” or “rock comet” — a rocky core that has lost the ices and gases that typically give comets their tails, according to NASA. The small asteroid, which is little more than 3 miles in diameter, approaches so close to the sun that it was named for the son of the sun-god Helios, who in Greek mythology lost control of his father's chariot and set the Earth ablaze.
What other meteor showers are happening in 2025?
Just one more meteor shower is due to peak before the end of 2025. The Ursids are due to become active between Dec. 16-26, peaking Dec. 21-22.
The Quadrantids will also begin in 2025 on Dec. 26, but the shower will not peak until Jan. 3, 2026.
Can I see the Geminids near Reno?
Though there are parts of Reno likely dark enough to see the Geminids, there are destinations nearby that provide darker skies and, as a result, better views of the meteor shower peak. Here are a few:
