    The European Space Agency announced on the 10th: a "house-sized" asteroid will be October 12 with the Earth "passing by."
    scientists have confirmed that the close encounter will not cause damage to the Earth, but will help test and evaluate the response capabilities of the Astro Impact Defense System.
    The near-Earth asteroid code-ed "2012 TC4" will orbit about 44,000 kilometers from Earth, equivalent to one-eighth of the Distance from Earth to the Moon, while the Geosynchronous Satellite orbits 36,000 kilometers above the ground, making it a "perfect miss."
    We are convinced that the object could not have hit the Earth and that there would be no danger," Detlev Koschini, a member of the European Space Agency's Near-Earth Object Research Group, was quoted as saying by AFP.
    this fall is not the first time it has "passed" the earth.
    October 2012, the asteroid, 15 to 30 meters in diameter, "skimmed" the Earth at a speed of 14 kilometers per second and entered the vast universe.
    was twice as far away as this prediction, and scientists predicted it would have another "near-Earth encounter" this year, but it was not clear how close it would be.
    now, with the help of the European Southern Observatory's new "God" very large telescope in Chile, scientists have been able to track its trajectory.
    said in a statement from the European Space Agency that the observation of the 2012 TC4, which skimmed the Earth at close range, provided an excellent opportunity to "test the ability of international cooperation to detect and track near-Earth objects and to assess the ability of countries to jointly respond to real asteroid threats."
    NASA announced on June 30th that it had approved a plan to prevent asteroids from hitting Earth into the preliminary design phase, with plans to launch spacecraft to hit a pair of asteroids in 2020 to change their orbits.
    , a unit of the Russian space group said it would begin building a near-Earth asteroid search and tracking system in 2019 to provide timely warning of potential impacts.
    astronomy community estimates that there are millions of asteroids in the solar system, most of which travel between Mars and Jupiter's orbit.
    the probability of an asteroid hitting Earth is small, but not without it.
    1908, an explosion believed to have been caused by a falling asteroid exploded over Tonguska in Russia's Siberian region, causing the largest object disaster on Earth in recent history.
    In 2013, a meteorite about 20 meters in diameter exploded over the Russian city of Chelyabinsk, releasing the equivalent of about 30 atomic bombs dropped on Hiroshima, causing damage to thousands of buildings and injuring thousands of others, without any warning from space agencies.
    'm not in danger this time, what about next time? The European Space Agency speculates that if an asteroid the size of "2012 TC4" does enter the Earth's atmosphere, "its effects could be diacritized by the Chelyabinsk event."
    , who runs Germany's European Space Operations Centre, has warned that humans are not ready for the threat of an asteroid hitting the Earth.
    said he would not lose sleep over the "2012 TC4" pass, "at least not this time."
    " but you can't help but think about what will happen next time... I would have felt more at ease if I had given an early warning.
