Meteor? Meteoroid? Meteorite?

What is the difference Meteor? Meteoroid? Meteorite?

To answer this, we begin by discussing, what is a meteor. What's the difference with a meteorite? What about meteoroids?

Meteoroids are celestial bodies that float freely in space. Forms and their movements erratic, relatively small size. And its movement is free and there is erratic in the empty spaces of space, one time it approaches the planet's orbit meteoroids. When approaching the orbit of the planet, say the planet Earth that we live, interact with the Earth's gravity pull of the meteoroid. Earth's gravity will make a much bigger meteoroids gravitate toward Earth.


Meteoroids are attracted by the pull of the Earth and will enter the Earth with very high speed. If the Earth did not have a layer of atmosphere, the meteoroid, tell of the coconut fruit size, will hit the Earth with tremendous force. You may feel the "strength" of rain water droplets to the top of your head. One drop of water that falls freely overwrite your head, still felt strong enough. How about "if" Earth without the atmosphere, and meteoroid enters the Earth with free fall, hit the Earth? With the higher speed, the greater the energy that is created, Booom ...

Earth is still fortunate to have the atmosphere that serves as a shield which is very tough. When the meteoroid enter into the Earth, Atmosphere will restrain the rate of meteoroid, but the rate of meteoroid continues to penetrate the layers of the Atmosphere. Friction between layers of the Atmosphere and erode Meteoroids and "burn" Meteoroids so that we on Earth see it as a Falling Star. Meteoroid that crashed and burned in the Earth's atmosphere is called Meteor. Is there a connection when there is a meteor, and we say our desire to come true? :)

During the burn in the atmosphere, we were treated to beautiful scenery Falling Star. Not every night we could see this beautiful scenery. So, luckily, if you see this natural phenomenon.

In the process enters the Earth, some parts of the Meteor eroded by atmospheric layer so when it arrive at Earth, the part becomes very small, much smaller than the original size. Even for the small size of the meteoroid, probably when they arrive on Earth just to live the rest of the dust alone. Meteor, which arrived on Earth is called a meteorite, we can see it in the Museums of Geology. 
There you can see the meteorite, meteorites visit to our planet Earth. If you see a meteorite the size of a tennis ball, how size when it was floating in free space?


Then if our Earth is safe from the spacecraft's guests as well as this Meteor? Is not there a very tough atmosphere to protect the Earth and the creatures that inhabit it?

Have you ever watched the Armageddon movie starring Bruce Willis? Hmmm ... imagine the celestial body that much, hit the Earth ... crushed all. Perhaps this is also causing havoc on Earth Dinosaurs. Several theories menerangkan Meteors hit the Earth and causing havoc living beings who inhabit it.

Remember the Schoemaker-Levy comet that hit Jupiter? From satellite observations in mind that this comet-hole damage caused by the planet Earth! Fortunate that this comet was hit by the giant Jupiter many times the size of planet Earth. If this comet hit Earth, our planet is gone. We will not be able to say it was beautiful when Meteor meteor comes greater than our own planet. I just hope this never happens, although we are not as safe as the planet Earth envisioned.

Let's take a more listening and enjoying the scenery and enjoy this natural phenomenon as a gift of God Almighty. There are various kinds of natural phenomena which unfortunately for us pass. Star or Comet  beauty, or the Morning Star is also the Planet Venus, eclipse, Aurora, Falling Star or Meteor, Meteor Rain (the arrival can be predicted and enjoyed throughout the year) and others.
