Giant Asteroid Approach the Earth, How Danger

Giant Asteroid Approach the Earth - This is a story about the asteroid. Objects from outer space, that now talking by many people will be touched by the earth. Early February, the Russian scientists estimate that an asteroid will hit Earth, 13 April 2036. Objects like rocks along the 269 meters was named Apophis.

Not yet completed preparations for Apophis, new threats come again. This time, according to experts from the U.S. space agency (NASA) in the United States. Asteroids of 460 feet, about 140 meters will be touched by the Earth on February 5, 2040.

Friday, March 2, 2012, a number of international television broadcast bustling simulation of NASA, about the collision. Asteroid is named AG 5 2011.

Studied since hundreds of years ago, to this day little is known about how experts process of formation of the asteroid. Some experts say that the asteroid was a remnant of a planet destroyed by explosions or crashing into other objects.

But other experts argue that possibility. According to them, the asteroid is a stand-alone objects, outstanding in space and can be withdrawn planets including Earth gravity. Conflicts can occur.

And lately, there's a lot of the universe circulating near the earth and some are touched. Whether because of increasingly frequent - as reported by the Daily Mail, February 28, 2012 - United Nations (UN) seriously discuss the asteroid.

The world body does have a unit called the Near Earth Object Action Team. This team, for example, has begun to discuss how the transfer orbit this giant rock that is not touched the earth. So that the damage can be avoided.

The team continues to discuss with experts from NASA. And based on the space agency's calculation, the chance that a large hard object hitting the Earth is 1:625. But Donald Yeomans, head of Near Earth Object Observation Program at the Jet Propulsion Laboratory of NASA, adding that the predictions that could change. Because it is also constantly changing.

Although it does not cause the end of the world - because size is not so bad - it would be dangerous if pierced through the city. Loss of life will fall, though probably not much. Compare this with the asteroid that triggered the destruction recorded in the history of dinosaur species 65 million years ago. The size is nine miles over the width of the size of the 2011 AG5.

But again this is still preliminary calculations. For NASA scientists themselves are still groping scaling properties of the asteroid AG5. So the new size estimates while. They could only watch half of it.

Exact size of the new note between 2013 and 2016 is a time when astronomers were able to monitor the 2011 AG5 of land. From preliminary calculations it is known that in the year 2023, this object would "get away from the key hole" that protects the earth, before he pierced through the soil, possibly in a very small size.

Rescue scenarios

NASA and space scientists have prepared a precaution, touched each other in order to avoid the possibility, however small the possibility.

One of the rescue scenario is to send the plane of the earth to the asteroid. The aircraft was designed to give the effect of gravity, which is capable of directing the asteroid away from earth, over millions of light years.

Another option, just like the story in the movie "Armageddon". A satellite was prepared to crash it into the asteroid.

In addition to the two ways, the use of nuclear technology has also been discussed. But, fear not resolve the nuclear issue, and helping to create hail that leads to the earth.
