First of all, it’s probably not as big as you think it is. The object is roughly 40 meters in diameter, according to the ESA. A football field is 48.5 meters wide and 109 meters long.
For comparison, some of the other asteroids on the Risk List measure 900 and 375 meters in diameter.
The Risk List is probably not as scary as it sounds
The Risk List sounds daunting, right? But that simply means that ESA has calculated a non-zero impact probability.
By comparison, the threshold for action by space agencies is if an asteroid is determined to have a 1 in 100 chance of impact with the Earth — an order of magnitude different.
In addition to 2006QV89, there are 869 other near-Earth asteroids on ESA’s Risk List.
And if we were to freak out about every one of them, we’d never get any work done.
It’s still pretty far away
2006QV89 is currently 4.2 million miles away from us. If the asteroid does hit Earth, it wouldn’t be until September 9, 2019, at 7:03 a.m., ESA says.
Space agencies have been prepping for the worst
So you can stop freaking out now.
