Asteroid Apophis will Hit Earth in 2036

In Egyptian myth, Apophis was the spirit of evil that causes destruction, wanted to bring eternal darkness to the world.
A name that fits, according to astronomers, for the chaos that will hit the Earth from space. The experts are looking at 390-meter-sized asteroids found June 19, 2004, which has the potential to collide with the planet, and continue to remind the government to act.
NASA has estimated the possibility of this asteroid to hit Earth in the year 2036, would release more than 100,000 energy which detonated an atomic bomb on Hiroshima. Of thousands of square kilometers would be directly destroyed, but the whole Earth will see the effects of the dust released into the atmosphere.

And, experts say, there is little time to make decisions. At a meeting for the Near-Earth Objects (NEO) in London, scientists say it may take several decades to design, test, and make the technology needed to change the direction of the asteroid. Monica Grady, an expert in meteorites at the Open University, said: "This is not a question of when, not if, an object crashed into Earth. Many smaller objects hit the Earth's atmosphere, and have no impact. However, a NEO larger than 1 km (width), will hit Earth every few thousand years, and NEO is more than 6 km would destroy Earth's life, every few million years. We're in a period for a "large".

Asteroid Apophis is one constant in the supervision of NASA, because it potentially hit Earth. Apophis, also known as 2004 MN4, until the end of 2004, remains a possible asteroid collision with the highest in the year 2029. But the beginning of the year 2005 showed a decrease possibilities of radar data. And in a few months later, the possibility of collisions in the year 2036 is also declining, and eventually reach the comparative figures 1:45000

A 13-year-old child, a junior high school, succeeded in correcting the Apophis asteroid collision calculations. Collisions which, according to NASA originally estimated that only 1:45000, a ride comparison, because Apophis is expected to hit one of the satellites that surround the Earth.

Nico Marquardt calculations show that at the date of October 13, 2008, during a meeting closest to the Earth, Apophis would likely have crashed into one of the 40 000 existing satellites and orbital trajectory changes. These changes will happen in 2029 again, as it approached the Earth, because again the possibility of Apophis hitting the Earth will experience. Consequently in the year 2036, during a meeting with Earth, Apophis will hit Earth likely to be 1:450, or one hundred times higher than NASA estimates.
Alan Fitzsimmons, an astronomer from Queen's University said: "If Apophis pass us on the date 13 April 2029, then in 2036 Apophis will hit us."

Officially, NASA's party issued a news release about the possibility of Apophis collision. Outstanding news also mentioned that Nico Marquardt and NASA had reached an agreement, even NASA has acknowledged that there is an error in their calculations.

From the office of the Near-Earth Object (NEO) Program at NASA's Jet Propulsion Laboratory, Pasadena, Calif., stated that the NEO does not have to change the current estimate of the possibility of Apophis collision. Apophis will still have a low possibility of collision with Earth that is 1: 45 000 in year 2036. Even NASA's NEO program, especially from the states, the investigators they had not made any contact or correspondence with students.
In previous news, otherwise Nico Marquardt perform calculations on a possible collision between the asteroid Apophis with artificial satellites during close Encounter (nearest the meeting) with the Earth in the year 2029.

Unfortunately, in the year 2029 when the asteroid Apophis approaching Earth, the asteroid will not pass through the area near the main belt of geosynchronous satellites. In other words, the chance of collisions with artificial satellites, so far.
Therefore, consideration of a possible collision scenarios with fixed satellite will not affect the possibility of collisions that have been taken into account this time, namely one in 45,000.

NASA, in particular the NEO program, tasked to detect and track asteroids and comets passing near Earth. They will find and calculate the trace of the object's orbit, to determine whether the incident was harmful to the Earth or not.
