14 DAY TRIAL // Asteroid 2013 TV135 passed by Earth about a month ago at a safe distance of 6.7 million kilometers (4.2 million miles). The problem is that it's coming back. In less than 20 years, the asteroid will once again cross paths with Earth's orbit and, that time around, it will be significantly closer. The asteroid is about 400 meters (1,300 feet) across.
So much so that we're already seeing doomsday headlines about the impending demise of our planet. Except the impending demise may not be that impending. NASA reassures that the asteroid, while coming quite close to Earth, won't pose any danger.
Based on the data so far, there's just a one in 63,000 chances of the asteroid hitting Earth. Put another way, there's a 99.998 percent possibility of it passing safely by.
The small chance of an impact is there because four weeks is too little time for a precise measurement. As more observations are made, a more exact trajectory will be calculated, one that is very likely to take the asteroid safely away from Earth.
And if that weren't to happen, the US and Russia will blow it out of the sky with nuclear weapons; maybe, hopefully not.
