It is expected, that 12 October 2017 asteroid 2012 TC4 will carry dangerously close to our planet. The exact distance of this passage is uncertain, as well as the exact size and composition of the celestial body.

On the basis of observations made in October 2012, when a space Guest flew past our planet, astronomers estimate that the size of it can vary from 12 to 40 meters. Recall that a meteorite that exploded over Chelyabinsk in February 2013, was about 20 meters in diameter. At the same time he became a damage over 7,000 buildings and injured about 1,500 people. Thus, the impact of 2012 TC4 can be much more devastating.

"We should not be staring at him - said University of Texas astronomer Judith Gorgiev-Rice (Judit Györgyey-Ries). - Perhaps we will see an explosion in the air, and rain will lead to damage of the meteorite remains - it all depends on the exact crash site" .

An asteroid the size of a house was opened October 4, 2012 Pan-starRS observatory in Hawaii. A week later he flew past the Earth at a distance less than the distance to the Moon - 94800 kilometers.

2012 TC4 is a rapidly rotating object elongated shape. It is not known how often he approached the Earth in the past. Now researchers are trying to determine the exact trajectory of the asteroid in 2017 and the likelihood of its impact on our planet. At the moment, the chances of falling regarded as 0.00055%.

"The probability that a celestial body can hit us - one chance in a million - said Dr. Detlef Koschny (Detlef Koschny), head of near-Earth objects in the department of space situational awareness ESA. - The size we can only tentatively identified by the brightness: this object maybe ten-and forty-meter. At the same time we do not know the composition of the asteroid. 40-meter iron body will pass through the atmosphere and will leave an impressive crater on Earth, and the 10-meter-high stone object simply burn up in the atmosphere, unnoticed. "

"Most likely, the asteroid poses no threat to Earth - assures Makoto Yoshikawa (Makoto Yoshikawa) from the Japan Aerospace Exploration Agency JAXA. - The distance is very small, but it does not mean that there will be a collision."

Even despite the fact that NASA experts also believe that the chances of a catastrophic collision no Gorgiev-Rice insists on additional observations that will reduce uncertainty.

Note that, as of April 12, 2015, found in 1572 potentially hazardous asteroids. However, none of the known asteroids in the near future face of our planet should not.
