The Geminid meteor shower, considered the most spectacular meteor shower of the year by astronomers, is set to reach its peak on December 13 and 14, 2023. Skywatchers across the Northern Hemisphere will be treated to a dazzling display as Earth passes through the trail of debris left behind by the asteroid 3200 Phaethon.
When and Where to Look for the Geminids
The Geminids can produce over 100 multicolored meteors per hour under ideal conditions (source). This year, the moon will be a waning crescent on the peak, meaning its light will not interfere as much with visibility.
The meteors will radiate from the constellation Gemini, which will be high in the southeastern sky after midnight. To see the most meteors, find an area with clear skies and minimal light pollution. Face southeast and look about two-thirds up the sky (source).
While the Geminids are visible from most areas, some of the best places in the U.S. to observe them include high-altitude regions like Colorado, New Mexico, and Arizona. The Pacific Northwest and upper Midwest also offer clear viewing opportunities.
What Causes This Cosmic Light Show
The Geminids occur each December when Earth passes through a trail of dusty debris shed by the asteroid 3200 Phaethon. As these dust particles enter Earth’s atmosphere, they burn up from friction with the air. This causes the bright meteors visible during the shower (source).
This asteroid orbits very close to the Sun, picking up material that eventually spreads into Earth’s path. The peculiar orbit of Phaethon sets the Geminids apart from other meteor showers caused by comets.
Why the Geminids Stand Out From Other Meteor Showers
The Geminids consistently produce a higher rate of meteors than many other annual showers. Up to 150 multicolored meteors can be visible per hour under excellent conditions (source).
While most meteor showers have a narrow peak, Geminid activity remains high for nearly two weeks in early-to-mid December each year. This gives skywatchers ample opportunity to spot meteors.
The Geminids also stand out for their variety of colors. While most showers produce white meteors from vaporizing debris, the diverse minerals in Phaethon’s dust produce vibrant colors including crimson, blue, green and yellow (source). The colorful “fireballs” make the Geminids a beautiful sight.
Viewing Tips for Geminid Meteor Shower
To prepare for Geminid meteor viewing:
- Find an area away from city lights with a wide view of the sky (source)
- Allow time for eyes to adjust to darkness by avoiding bright lights
- Face southeast where Gemini will be overhead
- Bring warm clothes, blanket, chair recliner and hot drinks to stay comfortable
- Be patient. Peak activity often occurs in the hours before dawn.

What’s Next After the Geminid Meteor Shower?
The brisk peak of the Geminids in mid-December closes an eventful season for meteor showers. But astronomy fans can look forward to the new year with bright Jupiter and Venus returning to prominence by February 2024 (source).
The famous “Evening Star” Venus will blaze after sunset, outshining Jupiter. Mars also makes a close approach in early January 2024, meaning all three planets beam together in the southwest sky.
While meteor showers take breaks until April’s Lyrids, there are still plenty of celestial events like eclipses, comets and moon phenomena to observe. So keep looking up!
