Group slots like NASA and ESA track a large number of objects near Earth on a daily basis, and many of them have the opportunity to make a miserable life if one day ends in the collision course on Earth. Potentially dangerous "asteroids often pass on Earth without issue, and both are likely to be true on September 9, 2019.
That's when the rock known as the 2006 QV89, an asteroid measuring more at 160 meters wide, is set to take the nearest Earth approaches for some time. Astronomers keep track of things believing that it can only get nearly four million miles, but the ESA says that there is a very small chance which may end here on Earth.
The ESA risk closure database relies on models and calculations based on past observations, and these measurements are usually very accurate. However, there is always a small the opportunity they are not seeing, and a smaller chance that they are off by enough impact occurs.
For the asteroid 2006 QV89, the chances of a y slim, but present. According to the ESA, the asteroid has a 1
The good news here – apart from the fact that there is almost no possibility of reaching Earth – is that while the rock is rolling closer it will give researchers more time to track its orbit and plan its course with higher accuracy.
