Dark, clear winter nights provide excellent conditions for stargazing and meteor watching. As Earth orbits the Sun, it passes through a stream of cosmic debris left behind by comets and asteroids. When these tiny particles hit Earth’s atmosphere, they create streaks of light known as meteors.
The month of December offers several notable meteor showers, including the Geminids and the Ursids.
Geminid Meteor Shower
- Peak: December 13-14
- Radiant: The constellation Gemini
- Zenithal Hourly Rate (ZHR): 120-150 meteors per hour
The Geminids are one of the most reliable and prolific meteor showers of the year. They are known for their bright, fast-moving meteors. The shower is caused by debris from the asteroid 3200 Phaethon, which is believed to be an extinct comet.
Ursid Meteor Shower
- Peak: December 21-22
- Radiant: The constellation Ursa Minor
- ZHR: 10-20 meteors per hour
The Ursids are a less active meteor shower, but they can still produce some impressive fireballs. The meteors are often slow and appear to drift across the sky. The shower is caused by debris from the comet C/1983 N1 (Shoemaker-Levy 9), which famously collided with Jupiter in 1994.
Other
In addition to the Geminids and Ursids, there are several other minor meteor showers that may be visible in December, including:
| Meteor Shower | Peak | Radiant | ZHR |
|---|---|---|---|
| Quadrantids | December 27-28 | The constellation Boötes | 40-80 |
| Minor Ursids | December 20-26 | The constellation Ursa Minor | 10-20 |
| December Leonids | December 2-7 | The constellation Leo | 10-20 |
Tips for Meteor Watching
- Find a dark location with clear skies.
- Avoid light pollution from cities or streetlights.
- Allow your eyes to adjust to the darkness for at least 30 minutes.
- Be patient and don’t expect to see meteors immediately.
- Lie down or recline on a comfortable surface to maximize your field of view.
- Use a star chart or mobile app to help you locate the meteor showers’ radiants.
Frequently Asked Questions (FAQ)
- What is a meteor? A meteor is a streak of light caused by a small particle of debris burning up in Earth’s atmosphere.

Best Time of Year to See Geminids Meteor Shower
The Geminids meteor shower is best viewed between December 7th and 17th, with the peak usually occurring on or around December 14th.
During this time, up to 120 meteors per hour can be seen at their radiant point, which is located in the constellation Gemini. The shower is best observed between midnight and dawn, with clear skies and little to no light pollution offering the most optimal viewing conditions.
Where to See the Geminids Meteor Shower
Optimal Viewing Conditions:
- December 13-14 (peak)
- Dark, clear sky
- Minimal light pollution
- Clear horizon to the southeast
Best Viewing Locations:
- Northern Hemisphere:
- Southern Canada and northern United States (e.g., Maine, New Hampshire, Vermont)
- Western Europe (e.g., England, Scotland, Ireland)
- Eastern Russia (e.g., Siberia)
- Southern Hemisphere:
- Southern Australia (e.g., Victoria, South Australia)
- New Zealand (e.g., North Island, South Island)
Tips for Viewing:
- Allow your eyes to adjust to the darkness for at least 20 minutes before looking up.
- Lie down on a blanket or reclining chair to maximize your field of view.
- Avoid using bright lights or screens that can interfere with night vision.
- Look towards the southeast horizon, where the radiant of the meteor shower is located.
- Be patient and enjoy the celestial spectacle, as meteors can appear randomly throughout the night.
How to Photograph the Geminids Meteor Shower
Equipment:
- DSLR or mirrorless camera with manual mode
- Fast, wide-angle lens (e.g., f/2.8, 14-24mm)
- Sturdy tripod
- Remote shutter release (optional)
Settings:
- Aperture: f/2.8-f/4 (to allow maximum light in)
- Shutter speed: 15-30 seconds (for clear meteor trails)
- ISO: 1600-3200 (to increase sensitivity)
- White balance: Tungsten or Auto
Technique:
- Find a clear, dark location with minimal light pollution.
- Set up your camera on a tripod and level it.
- Point the lens towards the constellation Gemini, where the meteors will originate.
- Use a wide composition to capture as many meteors as possible.
- Take continuous shots with the remote shutter release or shoot in bulb mode.
- Adjust the exposure settings as needed, monitoring the histogram to ensure proper exposure.
Tips:
- Shield your lens from direct light sources.
- Use a flashlight with a red filter to check settings without interfering with dark adaptation.
- Be patient and shoot for several hours, as meteor activity can be intermittent.
- Consider stacking images to enhance the visibility of faint meteors.
Geminids Meteor Shower History
The Geminids meteor shower is a relatively young meteor shower, first observed in 1833. It is associated with the asteroid 3200 Phaethon, which is believed to be the parent body of the meteoroid stream that produces the shower.
The Geminids are known for their high activity, producing up to 120 meteors per hour at their peak. They are also known for their bright, colorful meteors, which often leave behind persistent trains.
The Geminids are visible from mid-November to mid-December, with the peak of the shower occurring on December 14th. They are best viewed from the Northern Hemisphere, but can also be seen from the Southern Hemisphere.
Geminids Meteor Shower Astronomy
The Geminids meteor shower is an annual astronomical event that occurs every December. It is caused by the Earth passing through the debris trail of the asteroid 3200 Phaethon. The Geminids are known for their brightness and high frequency, making them a popular target for meteor watchers.
The Geminids are best viewed from the Northern Hemisphere, where they are typically visible from mid-December to mid-January. The peak viewing night is usually around December 13-14, when the shower can produce up to 120 meteors per hour.
The Geminids are a relatively young meteor shower, having been first observed in the 1860s. The source of the meteor shower was not identified until 1983, when astronomers discovered that it was associated with the asteroid 3200 Phaethon.
Phaethon is a unique asteroid that has a very elliptical orbit that takes it close to the Sun. When Phaethon passes close to the Sun, the Sun’s heat causes the asteroid to shed dust and debris. This debris forms the Geminids meteor shower.

Geminids Meteor Shower Meteors
The Geminids meteor shower, which occurs annually in mid-December, is renowned for its numerous and brilliant meteors. Originating from the constellation Gemini, the meteors are debris from an extinct comet known as 3200 Phaethon.
- High Activity: The Geminids are one of the most prolific meteor showers, with an average of 120 meteors per hour at their peak.
- Bright and Colorful: Geminids are known for their bright and colorful meteors, with many displaying hues of blue, green, and red.
- Fast and Fragile: Geminid meteors enter Earth’s atmosphere at speeds of around 22 miles per second and are relatively fragile, resulting in frequent fragmentation and persistent trains.
- Low Rate of Fireballs: Unlike other meteor showers, Geminids produce a low number of fireballs, with only a few occurring each year.
- Best Viewing Conditions: The Geminids are best observed during clear, moonless nights. The shower typically reaches its peak on December 14 (Eastern Time), with optimal viewing hours between midnight and dawn.
Geminids Meteor Shower Space
The Geminids meteor shower is an annual celestial event that occurs in mid-December, when the Earth passes through a stream of debris left behind by the asteroid 3200 Phaethon. The Geminids are known for producing a high number of bright, fast-moving meteors, and they are often considered to be one of the best meteor showers of the year.
The Geminids are named after the constellation Gemini, which is where the meteors appear to radiate from. The constellation Orion is located just below Gemini, and these two constellations provide a backdrop for the Geminids meteor shower.
The best time to view the Geminids meteor shower is between 10 pm and 2 am, when the radiant is highest in the sky. The shower typically peaks on December 13 or 14, but it can be seen for several days before and after the peak.
