How did Meteor Shower happen ?

There is Meteor, meteor showers, meteor storm, what's that all about?
What is a meteor shower and how did it happen?

Meteor is an incredible beautifully nature phenomenon. Meteor also called shooting stars. When the object space (meteoroid) enters the Earth and "burnt" due to friction with Earth's atmosphere, this is what we called the "Meteor". We on Earth see it as a falling star because of the light generated when entering our Earth. 

Then what is Meteor shower? Do you know what it is raining? :) 
Just as rain, meteor showers means there are Meteors coming in huge numbers into the Earth, like rain. Process of a meteor shower as well as the occurrence meteor process itself, only the occurrence of relatively large and at a time. 


In contrast to the occurrence of meteor itself can not be predicted, the meteor shower has its own schedule every year. Like for example if in the month of November, the planet Earth will be treated to spectacular natural scenery of the Leonid Meteor Showers incident. 

Why do meteor showers can be predicted while the meteors can not? We can tell when the meteor shower, we can also find out the various meteor showers. While the meteor incident itself until now very difficult to predict. Random movement of meteoroids patterns is complicate to estimates of meteor movement. While the occurrence of a meteor shower or when meteor shower occurs more predictable. 

Due to the occurrence of a meteor shower during the revolution of the Earth (ie the Earth on its axis for turning around the Sun), Earth is close to or penetrate the dust particles remaining from the tail of a comet ever approached the Sun. 

comet and meteor shower


Comet, during its circulation around the sun, leaving a trail of comet dust particles from the body itself. Remember that comet tails always away from the sun. Some part of comet that "blown  away" by the sun leaving the dust particles are always away from the sun. This is what looks like the tail of a comet. And during its circulation, for "blowing" the sun causes around the track filled with comet dust remaining comets continue to hover. 

If the dust particles are the remnants of this comet passes near Earth, and an area when the Earth crossed the comet's dust particles, the dust will be attracted by the pull of the Earth's force. During entering the Earth, dust is burnt in the atmosphere and we are located on Earth will see it as a "meteor shower". 

When the meteor shower  happen? Each year the meteor shower can be predicted her arrival because of the Earth through the area around the dust particles by the time the remains of comets that almost fixed. And the dust remains of the comet will remain there until exhausted. Or maybe will not going out on the left of dust particles because comet will be back again someday. 

International Meteor Organization routinely publish Meteor Shower Calendar which is going to happen every year. You can create a schedule and prepare all equipment to enjoy this incredible scenery. Thick jacket, a cup of coffee, snacks and do not forget the telescope if you want a clearer view of this meteor shower.
