20 10 Gemini meteor shower

Gemini meteor shower occurs every year, and its intensity is second only to that of Leonid meteor shower, the king of meteor showers. It originated from an asteroid discovered in 1983, and belongs to the burnt comet wreckage. However, unlike the short-lived Leonid meteor shower, the Gemini meteor shower usually lasts about 10 days.

Gemini meteor shower-causes

Gemini meteor shower Many familiar meteor groups are very old, such as Perseus and Leo. However, the Gemini meteor shower group is very young, and it only appeared in the middle of 19 century, and the flow was low at the beginning. Qingdao citizens catch 10-20 Gemini meteor showers every hour. Since then, its flow has been increasing every year, and now it has become the main meteor group every year. In 1998, the observed Gemini meteor swarm reached ZHR= 140 per hour. Observers with good observation conditions can see more meteors at most.

Since 1862, people have been looking for Gemini's mother comet. It was not until 1983 that the satellite discovered that it was not a comet, but a rocky asteroid with the same orbit. The number is 3200 Phaeton. The period of this asteroid is 1.4 years, and its orbit is very flat, and the nearest distance from the sun is 0. 15 astronomical unit. 1997 12 when it passes near the earth, it is only 0.35438+0 astronomical unit away from us.

People have been debating whether Phaeton is an asteroid or a comet. Its spectrum looks like a rocky asteroid, but its orbit looks like a comet. When it passed the sun, it had no tail, but it produced fragments and formed a meteor shower. By analyzing the photos of Gemini fireballs, scientists estimate that the density of Gemini meteors is 1-2m/cc, which is 3 gm/cc lower than that of standard asteroids, but several times higher than that of comets. Some people think that Phaeton is a depleted or dormant comet with thick interplanetary dust on its outer surface. So it will have the appearance of an asteroid, but the core is a comet.

In 2009, the Gemini meteor shower will last from 65438+February 7th to17th. In 2009, the Gemini meteor shower will reach its peak between the night of 65438+February 14 and the early morning of 65438+February 15.

Gemini meteor shower-observation time

Gemini meteor shower For those who are willing to watch the meteor shower in the cold, Gemini meteor shower is a very distinctive scenery in winter, even surpassing the Perseid meteor shower in August+February 65438+March 3. Astronomers David and Steven said, "If you have never seen a Gemini meteor group draw a clear arc in the vast night sky, then you can't say that you have seen a meteor."

So, when is the best time to watch the Gemini meteor group? It depends on your position. As soon as night falls, Alpha Gemini begins to appear on the horizon in the east or northeast, so you'd better stay outdoors until the moon rises.

During this period, you may also see a distinctive ground-skimming meteor, which appears from the horizon (sometimes even below the horizon) and drags its long tail across the atmosphere almost horizontally. Therefore, the best viewing time is from midnight to midnight, and the night falls until the moon rises.

It is a long and cold thing to watch the meteor swarm in winter, so we must wait patiently for the appearance of the meteor swarm. If they haven't appeared yet and you feel terribly cold, then you may not last long. Therefore, make sure you can observe the meteor swarm in a warm and comfortable environment.

Gemini meteor shower is a very reliable meteor shower, which appears regularly every year. Gemini rises in the evening and remains high in the sky until dawn, visible all night.

Astronomical experts said that a striking feature of Gemini meteor shower is its high brightness, medium speed and rich colors, which is very attractive to visual observers, and the number of meteors is also more than that of Leonid meteor shower last month. Under ideal sky conditions, the number of theoretical zenith meteors per hour is about 120. [ 1]

Gemini meteor shower-wonders ranking

Gemini meteor shower 1, quadrant meteor shower: it is a meteor shower that occurs at the beginning of each year. Meteor shower has moderate speed, high brightness and blue color, which is very suitable for observation. The quadrant meteor shower of 20 10 is likely to occur at about 3: 00 Beijing time1October 4.

2. Lyra meteor shower: Lyra meteor shower 20 10 is active in the middle and late April, and the maximum time is in the evening of April 22, Beijing time.

3. Aquarius meteor shower: Yan Jiarong, an astronomical expert from Jiangsu Astronomical Society, reminded that the observation conditions in the southern hemisphere are more favorable than those in the northern hemisphere, and the observation time is longer than that in the northern hemisphere.

4. Perseid meteor shower: It is not only numerous, but also the most active and frequently observed meteor shower, ranking first among the three periodic meteor showers. Yan Jiarong introduced that from 23: 00 on August 2065438+00 to the early morning of the next day, a splendid starry summer night drama will be presented to the public.

5. Leonid meteor shower: The best observation time of Leonid meteor shower at 20 10 is 18, and there will be 20-50 meteors across the night sky every hour before dawn.

6. Gemini meteor shower: The Gemini meteor shower in 20 10 will reach its maximum in the early morning of 65438+February 15, and the maximum number of meteors per hour can reach about 120, which can be observed all night. [2]

Gemini meteor shower-observation precautions

1, safety issues are the first, including traffic safety and safety during observation. Resolutely don't burn the midnight oil, don't drive fatigue, arrive at the observation site during the day and find out the surrounding environment. Try to choose a farm house far away from water, roads and railways, and make sure whether the dog is tied properly.

It is winter now, and the temperature is very low in the second half of the night. To enjoy the meteor shower, you should "arm" with thick clothes from head to toe.

Don't forget to have a rest. Sitting and lying down while watching the meteor shower can relieve fatigue. Chairs and damp-proof mats are necessities. At the same time, it is necessary to replenish food and hot water in time.

4. The better observation place is a place far away from urban light pollution and at a higher altitude. [3]
