Space groups such as NASA and ESA daily track a huge number of Earth-like sites, and many have a chance to make life worthless if one day collide with the Earth. These "potentially dangerous" asteroids regularly cross the Earth without a problem, and the same is likely to be true on September 9, 2019.
Then the rock, known as the QV89 2006, an asteroid with dimensions over 160 feet wide, has to get closer to the Earth for a while. Astronomers who track the site believe they will only reach four million miles, but according to ESA there is little chance of ending here on Earth.
The ESA's risk tracking database relies on models and calculations based on past observations and these measurements are usually very accurate. However, there is always a small chance that they are not in place, and an even lesser chance that they are off enough to get impact.
For the asteroid 2006 QV89, the chance of impact is small but present. According to ESA, the asteroid has a chance 1 to 7,300 to hit right on our planet. With a width of 164 feet, the asteroid is not exactly a "killer on the planet," and even to hit the Earth, it will not be the end of the world. Yes, if it hit land, especially in a heavily populated area, it could cause very serious damage. If it hit the sea, it could even cause the tsunami to form.
The good news here – besides the fact that there is little chance of striking the Earth – is that as the rock approaches, it will give researchers even more time to track their orbit and plan their course with a higher degree of accuracy.
