TUGAS 4 BAHASA INGGRIS BISNIS 2 : NASA news : This year our earth will be attacked by meteors or asteroid? Is it true?

As the article published by www.techno.id the NASA statement on the Earth will be hit by asteroid. NASA stated that the asteroid will hit earth in March.

This is the complete article :

Is it true that Earth will be hit by an asteroid in March later?

Some theories say that the Earth will be destroyed after being hit by a large-sized asteroid. After investigation, NASA's answer ...

Techno.id - Various theories and predictions about the end of life on earth to burst in a variety of media. One emerging theory is the destruction of the Earth after being hit by a large asteroid. But again a scientific study dispelled that theory.

As reported by CNET on Wednesday (02.03.16) and then, NASA returned to announce the results of its research. NASA says that the planet will be visited by an asteroid in March.

The asteroid named 2013 TX68, space objects that have a length of 30 meters was once rumored to be hit Earth. It is true that the asteroid will be visiting Earth, but only through the course, and not hit it.

In 2013 then, NASA managed to detect the presence of this asteroid when it is within 14 million km from Earth. When passed in March, the asteroid will be in a safe distance is 17,000 km from Earth.

NASA scientists also say that there is no possibility that the asteroid will hit the Earth. They also add that, even if the asteroid hit the Earth, would make mankind extinct from the face of the Earth

Since a long time ago our earth frequented by visitors from outer space. but were just passing by, or landing on Earth's surface. Even them are thought to trigger the emergence of life and create an ecosystem that can sustain life until now. We're talking about celestial objects called asteroids, meteorite or comet. Celestial objects that is believed to create an ecosystem on Earth.

Thousands of meteorite rained down on Earth every year. Just because the size is very small, this meteorite has been destroyed when it entered the atmosphere. Some of them may still remain and fell to Earth. When the asteroid that crashed into the surface of the water, it will float for a moment and if the asteroid touching the bottom of the ocean, he would explode creating a crater measuring 11 miles. Water waves will fly several miles into space, with heights reaching levels that can be achieved jets. If you've seen the movie Deep Impact, that is exactly what happened.

Real incident on June 30, 1908, when a meteorite is only 60 meters in diameter, exploded at an altitude of 15 kilometers above the Tunguska forest in Siberia. Within a radius of 60 kilometers homes as if shaken by the catastrophic earthquake. And in a radius of about 20 kilometers from the center of the explosion, burning forests and shattered. Or the creation of a diameter of one kilometer meteorite crater in Arizona USA, which is the impact of the fall of an iron meteorite diameter of 100 meters at 20,000 years ago.

So far the experts also predicted extinction of dinosaurs 65 million years ago, is due to the fall of an asteroid 10 kilometers to the Yucatan peninsula in Mexico. Formerly impact does not threaten humans. Because when the dinosaur extinction, people completely not exist on Earth. While 20,000 years ago Arizona is an empty area uninhabited by humans.

In the solar system, the asteroid belt located between Mars and Jupiter. However, if there are other styles of the universe, for example, there are comets that pass or asteroid collision occurred, then a few pieces of asteroid it off from its tracks and may be entering the Earth's gravity. If the object is large enough, the celestial bodies can survive, and the possibility of falling to Earth. When that a small object, usually burn out in atmosphere.

The relatively small asteroid or meteorite enters the Earth's gravity, causing often go unnoticed by the experts. Diameter of approximately one kilometer to the celestial bodies is relatively small when compared with the satellite or planet and the star are very large in size. Admittedly, astronomers often only managed to see his example, that a meteor or asteroid just across the Earth. Thus, when these celestial bodies fell to Earth, experts are powerless to prevent it, because he was not able to trace it.

The asteroid hit Earth's estimates were not the first. In fact the asteroid as big as a refrigerator entered the Earth's atmosphere every year. Most asteroids burned while on the trip, and about two-thirds of the rest fell into the sea. That's because about two thirds of the planet is ocean. Smaller rocks plunging to the earth's surface on a regular basis. Interestingly, about a rock from Mars that fell to Earth each month.

However, the astronomers confirms that the astronomical phenomena as exposed above is normal and inevitable. The threat is indeed terrible, but it is a natural phenomenon that is reasonable and indeed a necessity. What is even more terrible that the destruction of the earth not because the asteroid, but because the act of inhabitants is taking place slowly but surely. The population of the earth is getting bloated, foodstuffs are increasingly depleted, pollution everywhere. The technology is already developed, but their use is not solely directed to human welfare, but more to fight other humans.

If it were so, phenomena astronomy as described above, seems to be seen as a warning to arouse our consciousness, that greed would not make eternal human.

so, as said by the scientists, we do not need to panic with a predictions of the phenomena on earth. we should appreciate what scientists has been done, however what scientist do is for the goodness of human beings and to prevent human from bad things. so, whatever they predictions, make them (predictions) as a precaution not as a belief and don't react with excessive fear.
