NASA asteroid WARNING: Asteroid discovered last week is headed for Earth approach TODAY
An asteroid this big is eight-times longer than a London double-decker bus and is 30-times the length of a Queen Size bed.
At the same time, 16-and-a-half Volkswagen Beetle cars could fit inside of the asteroid one after another.
Towards the lower end of the estimate, Asteroid BW1 is still 15-times longer than a Queen Size Bed.
Much smaller asteroids have caused considerable damage in the past when they stuck the Earth.
The most notable example of this is the 2013 Chelyabinsk Meteor, which exploded over Chelyabinsk Oblast in Russia six years ago.
