A meteorite twice the size of a comet explodes over Russia in 2013 and will approach Earth in September. The probability of a collision is considered very low.
Based on the results of orbital calculations, this asteroid will be closest to Earth at a distance of 6.8 million km. When the 2006 QV89 is closest to Earth, there is a 1/100 probability that it will suddenly change orbit and cause a disaster.
With a diameter of more than 50 meters, this type of asteroid will reappear in a few decades. In 2006 alone, the QV89 was monitored and photographed by scientists over 10 years ago.
In 2013, a comet from the dark area behind the sun exploded and blew up thousands of windows in Russia. Specifically, it was only discovered when it entered the atmosphere and exploded. From this event, scientists found that the most dangerous meteors often go undetected early on because humans cannot track all of the flying objects in space.
