On October 31st, 2016, we all almost died.

Well, maybe not died, but certainly lived in a world with no sun for months, fire and ash raining from the heavens above, and months of darkness. This could have been the outcome of the Halloween killer asteroid.

To the relief of the nearly 7.5 billion people on earth, this did not happen. Everyone woke up the morning after, looked out their windows, and saw the sun rising in the sky. Most did not know that they had “narrowly” escaped.

This was really just another day in space, considering how many life-on-Earth-ending asteroids pass near us every year. However, according to The Tracking News, a website that tracks celestial activity, this rock was fairly abnormal. The space rock measured an estimated 35 meters (115 feet) and was traveling 5.24 LD – which stands for Lunar Distance. Lunar Distance is the measurement from the moon to the Earth one time, which is roughly 238,000 miles.

If this asteroid had hit Earth, it surely would have caused some damage. Experts estimate that the explosion would be the size of a large nuclear bomb. Not a life-ending event like the 3 mile wide asteroid that famously killed the dinosaurs, but one that would make the skies rain ash and fire for months.

Compared to the Chelyabinsk meteor, which struck the atmosphere over Russia in early 2013 and injured about 1,500 people and damaged over 7,000 buildings, this asteroid would have been much more serious. The Russian meteor was almost equivalent to 300,000 tons of TNT, while the Halloween asteroid could have carried a force of over 100 kilotons.

The unlikely event would have crippled the Earth, so be glad that this did not happen this year. In the future, as you spend Halloween on the lookout for clowns, ghouls, and demons, keep in mind that asteroids from above just might be looming as well.
