Space groups like NASA and ESA track a huge number of near-Earth objects on a daily basis, and many of them have a chance to make life miserable if they end up on a collision course with Earth. These "potentially dangerous" asteroids regularly pass Earth without issue, and the same will probably be true on September 9th, 2019.
That's when the rock known as QV89, an asteroid measuring just over 160 feet wide, is set to make its closest approach to Earth in some time. Astronomers who have been tracking the object believe it will only get as close as four million miles, but ESA says there's a very tiny chance it could end up here on Earth
ESA's risk-tracking database relies on models and calculations based on past observations, and those measurements are typically very accurate. (1
The good news here – besides the fact that there is almost no chance of it hitting Earth – is that as rock moves closer it will give researchers even more time to
