不管Phaethon的起源如何，观测结果显示，双子座的流量比大多数流星雨要大，使它们在燃烧之前能够低至地球表面以上29英里。其他流星雨，如英仙座流星雨，燃烧得更高。世界上大部分地区都可以看到双子座流星雨。然而，北半球将最适合观测双子座流星雨。The Gemini meteor shower is caused by a fragment of a celestial body called 3200Phaethon, and its origin is somewhat controversial. Some astronomers believe it is an extinct comet because observations show that a small amount of material has left the surface of Phaethon. Others think it is an asteroid because of its orbit and its similarity to the main belt asteroid Pallas.
“Regardless of the origin of Phaethon, observations show that Gemini has a larger flow rate than most meteor showers, allowing them to be as low as 29 miles above the earth’s surface before burning. Other meteor showers, such as the Perseid meteor shower, burn even higher. The Gemini meteor shower can be seen in most parts of the world. However, the northern hemisphere will be best suited to observe the Geminid meteor shower.
In addition to the weather, the phase of the moon is also the main factor that determines whether a meteor shower will have a good flow in any year. This is because moonlight “washes out” the darker meteors, causing sky observers to see fewer bright meteors. This year, during the maximum period of the Gemini meteor shower, the moon is almost full 80% of the time, which is not ideal for our high-profile meteor shower.
Bill Cooke, head of NASA’s Meteorological Environment Office at the Marshall Space Flight Center in Huntsville, Alabama, said: “The Geminid meteor shower is rich in green fireballs and is the only meteor shower I would like to see on a cold December night. ”
NASA will broadcast the great moments of the meteor shower on December 13-14 through the meteor camera at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
The all-weather meteor shower videos recorded by Fireball Network can also be watched every morning. Identify Gemini meteor showers in these videos-just look for events marked “GEM”.

Why are they called Gemini meteor showers?
All meteors related to meteor showers have similar orbits, and they all seem to come from the same place in the sky, which is the so-called radiant point. The Gemini meteor cluster seems to radiate from a point in Gemini, so it is called “Gemini”.
How fast is the Gemini meteor shower?
The speed of the Geminid meteor shower is 78,000 miles per hour (35 kilometers per second). This is more than 1,000 times faster than the Cheetah, more than 250 times faster than the fastest car in the world, and more than 40 times faster than a speeding bullet! This is the speed of Gemini.
How to observe the Gemini meteor shower?
If it is not cloudy, stay away from bright lights, lie on your back and raise your head. Remember to adjust your eyes to the darkness-so you will see more meteors. Keep in mind that this adjustment may take about 30 minutes. Don’t look at your phone screen, because this will destroy your night vision ability. The public can choose a place with a wide view, safe and no light pollution.
Observing in a city with a lot of light pollution will make it difficult for you to see the Gemini meteor shower. In this case, you may only see a few at night.
When is the best time to observe the Gemini meteor shower?
December 13/14 is the best time to watch the Gemini meteor shower. Sky observers in the northern hemisphere can go out to watch the Gemini meteor shower in the middle of the night on December 13, but due to moonlight and other influences, you may not see many meteors.
You can still see Gemini meteors on other nights before or after December 13-14, but the number will be much less. The last Gemini meteor can be seen on December 17.
How many Gemini stars can observers see on December 13/14?
In reality, observers in the northern hemisphere expect to observe about 30-40 meteors per hour. Observers in the southern hemisphere will see fewer meteors than those in the northern hemisphere–perhaps 25% of the number observed in the northern hemisphere.
