Space groups such as NASA and ESA track a large number of objects near the Earth every day, and many of them have a chance to make life unhappy if one day they end up on a collision course with Earth. These "potentially dangerous" asteroids regularly send the soil without problems, and the same is likely to be true on September 9, 2019.
This is when the 2006 mountain QV89, an asteroid measuring over 160 meters wide, is set to do its closest approach to the earth for some time. Astronomers who track the object believe that it will only be as close to four million miles, but ESA says there is a very small chance that it may end up here on earth.
ESA's risk-based database is based on models and calculations based on previous observations, and these measurements are usually very accurate. But there is always a small chance that they are not spot-on, and an even less chance that they are off with enough for an effect to occur.
For asteroid 2006 QV89, the risk of impact is narrow but present. According to ESA, the asteroid has a 1
The good news here – besides the fact that there is no chance that it hits the ground – is what rock moves closer to it will give researchers even more time to track their course and draw the course with a higher degree of accuracy.
