The Geminid meteor shower is one of the finest meteors showers visible in either the Northern or the Southern Hemisphere. 

From December 4 to December 17, the Geminid meteor shower will be active, reaching its peak meteor production on December 14th.

Over this period, there will be a chance of seeing Geminid meteors whenever the shower's radiant point – in the constellation Gemini – is above the horizon, with the number of visible meteors increasing the higher the radiant point is in the sky.

The Geminids, as their name implies, appear to emanate from the bright constellation Gemini (the twins). To find Gemini, look in the northeastern sky for the constellation Orion, which is easy to spot by the three stars in the hunter's "belt." Then look just up and to the right of Orion to see Gemini, high in the northeastern sky. Although the meteors will appear to stream away from Gemini, they can appear all across the sky.

The Geminids are associated with the near-Earth object 3200 Phaethon, an asteroid that may have undergone a collision with another object in the distant past to produce the stream of particles that Earth runs into — creating the meteor shower. 

The asteroid orbits the sun every 1.4 years. It occasionally comes close to Earth (at a safe distance) and also passes very close to the sun, inside of Mercury's orbit and only 0.15 astronomical units from the sun. 

Geminid Meteor Shower: When, Where & How to See It

This year's Geminids may be difficult to see because of the bright moon.

The American Meteor Society claims that skywatchers can view up to 150 meteors per hour during peak hours without moonlight. However, the moon will interfere with the Geminids this year since it will be 70% lighted, outshining fainter meteors.

Anywhere in the Northern Hemisphere is good, but the shower is visible from the Southern Hemisphere too.

You will want to find a big open space where you can see as much sky as possible.

Check the weather, as clear, cloudless skies are best.

The peak activity of the meteor shower is predicted to occur around 08:00 EST on December 14, 2022, thus the greatest displays may be visible before sunrise.

The Royal Observatory advises: "For the best conditions, you want to find a safe location away from street lights and other sources of light pollution."

The Geminids are considered one of the best meteor showers every year because the individual meteors are bright, and the peak can see meteors stream across the sky at rates as high as 120 meteors an hour. Under light-polluted skies, fewer meteors will be visible. [Geminid Meteor Shower Awes Skywatchers Worldwide (Photos)]

The Geminid meteor shower is nearly 200 years old, according to known records — the first recorded observation was in 1833 from a riverboat on the Mississippi River — and is still going strong. In fact, it's growing stronger. That's because Jupiter's gravity has tugged the stream of particles from the shower's source ― the asteroid 3200 Phaethon ― closer to Earth over the centuries.

When to see them

The meteors tend to peak about 2 a.m. local time.

The Geminids, as their name implies, appear to emanate from the bright constellation Gemini (the twins). To find Gemini, look in the northeastern sky for the constellation Orion, which is easy to spot by the three stars in the hunter's "belt." Then look just up and to the right of Orion to see Gemini, high in the northeastern sky.

Although the meteors will appear to stream away from Gemini, they can appear all across the sky. For best results, you should look slightly away from Gemini so that you can see meteors with longer "tails" as they streak by; staring directly at Gemini will just show you meteors that don't travel very far. 

Where do they come from?

The Geminids are associated with the near-Earth object 3200 Phaethon, an asteroid that may have undergone a collision with another object in the distant past to produce the stream of particles that Earth runs into — creating the meteor shower. 

The asteroid orbits the sun every 1.4 years. It occasionally comes close to Earth (at a safe distance) and also passes very close to the sun, inside of Mercury's orbit and only 0.15 astronomical units from the sun. (An astronomical unit is the distance between the sun and the Earth: about 93 million miles or 150 million kilometers.)

Rocks in space that are about to collide with Earth's atmosphere are called meteoroids. Those that streak through the atmosphere are called meteors, and if they reach the ground (which won't happen with the Geminids, as the particles are too small to survive the trip) the rocks are called meteorites.

How to get the best view

Meteor showers don't require binoculars or telescopes to view — just your bare eyes. Find a comfortable spot to lie on the ground, far away from lights and ideally in a dark-sky area. Bring a blanket and dress warmly if you're in cold weather. Give your eyes about 20-30 minutes to adjust to the dark, then sit back and enjoy the show.
