Not yet sure, whether the Earth will survive the asteroid Apophis, which according to Russian scientists going to hit Earth on 13 April 2036, new threats emerge.
U.S. space agency [NASA] to identify a space rock that has a chance to nudge the Earth. The amount of 460 feet or 140 meters. NASA called identification, which is named after the asteroid hit Earth in 2011 AG5 likely on February 5, 2040.
As published by the Daily Mail, February 28, 2012, the existence of this asteroid to the attention of even the near-Earth object action team formed by the United Nations [UN], which began to discuss how to divert the orbit of the giant stone so as not to nudge the Earth. So as not to endanger the human race.
Based on calculations presented Donald Yeomans of NASA, the Head of Near Earth Object Observation Program at the Jet Propulsion Laboratory, the chances of the asteroid with the Earth is 1:625 touched, predictions that can be constantly changing, as the movement is constantly changing. "Fortunately, this object will be observed from the ground in the interval 2013-2016," he said.
Although I will cause the end of the world and destroy mankind, skrenario worst, when it crashed into a celestial city, undoubtedly millions of lives will be lost.
For comparison, the asteroid that triggered the extinction of species of dinosaurs 65 million years ago, nine miles over the width of the size of the 2011 AG5.
So far, scientists are still groping, find out the nature of the asteroid's movement. The experts can only estimate the size, they can only observe the half-orbit.
The new between 2013 and 2016, astronomers will be able to monitor the 2011 AG5 of land, which became the capital to make a more detailed assessment.
At 2023, the asteroid will "get away from the key hole" to the Earth - in the area that passes through the orbit, before he finally hit the Earth.
According to NASA's Jet Propulsion Laboratory, momentum will be in 0:02 astronomical unit of our planet, or about 1.86 million miles.
What can be done to avoid catastrophe ?
NASA said, in between saving the Earth is an option to send the plane into the asteroids that could give the effect of gravity, to direct the 2011 AG5 away from the earth, over millions of light years.
Another option, is to send a satellite and an asteroid crashed into it.
The use of nuclear weapons was also discussed. However, it is feared, rather than solve the problem, it creates nuclear hail that leads to Earth.
Meanwhile, as published by SPACE.com, the asteroid was discovered in January 2011 by the Mount Lemmon Survey Observatory in Tucson, Arizona.
2011 AG5 is the object that currently has the highest chance of hitting Earth in 2040. However, we only studied for about half an orbit, so the precision of this calculation is still not very high, said Detlef Koschny of the Solar Division of the European Space Agency [European Space Agency], the Netherlands.
