.American astronomers predict an asteroid that size to 400 m will be removed to pull the earth's surface someday in the future. On April 13, 2029, a celestial mass that is now the astronomers called Apophis will scan the Earth at a distance of about one tenth the distance between Earth and Moon. Recently, experts at the University of Michigan report that the last time that an asteroid Monitoring progress near the Earth's surface at a distance like that happened 1300 years ago.
2004MN4 asteroid, called Apophis is currently located near the Earth's Best (the center of the Earth 30,000 km) and recently recorded in the listing with the number 99,942. This name was given to this asteroid on July 19, 2005. Also some of the dynasty pharaoh 15-16 century named Apophis. Today, the asteroid 99942 Apophis is only with numbers and names separately.
Recently, astronomers have observed from several observatories on Earth to determine the orbits of asteroids and other conditions make it move closer to the Earth's surface. Data collected allows astronomers to predict asteroid will impact Earth in 2029.
Last year, researchers have concluded that the asteroid is one of about 600 celestial bodies is be dangerous to Earth. According to provisional data, Apophis can one again Monitoring progress to the earth's surface in 2035, 2036 and 2037. This is the first researchers to assign the impact of the attraction from the Earth to the largest asteroids.
The researchers believe that the Earth's gravity and the attraction and on the inside surface of the asteroid can be destroyed from the natural. Observed it through telescopes and other devices allow scientists to study the structure of the asteroid and get all necessary information in case it threatens to impact the Earth.
There are regions in diameter is about 600 square meters with the attraction due to asteroids gravity force distribution in the solar system; when passing the area, the asteroid's orbit can be changed little. Apophis's orbit to fly above the earth in 2029, the scope is deflected several thousand km in each direction. The astronomers noted that there are three key holes in the corridor will change the asteroid's orbit and even trigger a crash expected to occur in 2036.
The asteroid is too small so hard to be able to destruction of life on earth. however the impact of it with a part of the earth can cause severe destruction in there. U.S. experts estimated that such a collision may cause damage to 400 billion dollars, and countless other scourge. Apophis can be seen on the territories of Europe, Africa and West Asia on the night of 2029.
NASA experts are preparing to build a nuclear missile to destroy or significantly alter the orbit of the asteroid. Thought that if such an intervention was launched to Apophis before 2029 is sufficient to alter the asteroid's orbit about 800 m to prevent collision with Earth in 2036. If desired, Apophis orbit must be changed to 13,000 km, but this result is extremely difficult task with modern technology.
