10. Comet and Meteor Shower

Leonid meteor shower of 1866 large meteor shower legendary, and 1833. I appeared thousands of meteors per hour.

    When do you look at the night sky? Perhaps, it's when celestial event occurred. Comet or meteor shower's a very grand event. And it is even artistic. People to set wallpaper on the computer a picture of meteor would also be large. In most cases, we can enjoy the celestial show without special equipment. 

    Comet's celestial body going through the night sky while pulling the tail. It's like a snow ball that was dirty. They begin to evaporate in the vicinity of the sun. So we can be observed that gas as the tail from the earth. In addition, the meteor is generated from comet often. Comet're moving through space while leaving the dust. Earth approaches the group of those dust, and the dust is going to fall to the Earth's surface. This is observed as a meteor shower. That these events occur in cycles, in many cases. Orbital motion is the reason of it. 

Gemini meteor shower.

    I introduce the meteor shower of the famous three. One is Gemini meteor shower. We can see this in December 14 before and after. Meteor of 30 from 20 per hour appears. This meteor shower is active in the same scale roughly every year. I can say that there is no hit or miss. Next up is Perseid Meteor Shower. This is active in 13 days after August. It is a meteor shower high-profile. It's because of overlap with summer vacation. I show the activities of the year's largest meteor of 60 from 30 per hour appears in this. Because it is the event of warm weather unlike the other two, I highly recommend you to everyone observation. 

    I introduce the Quadrantids last. It is also called Draco ι meteor shower. This is to work on January 4. Observation is difficult years of daytime peak for activity.And observable time is short. But it is suitable for the observation of the country good weather in the northern hemisphere. I regret that I did not introduce this meteor earlier. This is what these three are called the three major meteor shower. 

Trajectory of ISON comet.

    Because there is unevenness in the vanity and comets meteor shower the other, it is better to see the news of them on your own. It may not be possible to predict scientists. That ISON comet disappeared because this was too close to the sun is a pity. Large comet appears only once in a few years. You guys should not miss. 

    I've been told the charm the stars and the universe. I will be happy even if you guys were in love with astronomy.
