Polar, AlGrrrr should be worried about Trump dropping another MOAB and causing widespread Global Cooling in Afghanistan. All those warm bodies of ISIS will be cold soon enough.
An asteroid about 150 feet in diameter has a mass estimated at about 143,000 tons. Should an object that size hit the Earth, it would cause a blast with the energy equivalent of about 2.4 million tons – or 2.4 megatons – of TNT with an explosive force of more than 180 times the power of the atomic blast that leveled Hiroshima. It would level approximately 825 miles (2,137 square km. So maybe not an extinction event by if it hit a major city, a regional disaster that would have world wide repercussions.
825 miles divided by the entire square mileage of the LAND surface of the Earth is a very small fraction. Further, the square mileage of inhabited cities is relatively small compared to the square mileage of land on Earth. Hence, the odds of a meteor of the size you indicated – 150 ft in diameter – striking a city is very slim to none.
I’m more worried about a large cruise ship striking the iceberg on which I float around the ocean. Nearer My God To Thee, and all that stuff.
Nutty Professor Al Gore warns us that we will all drown long before Earth is hit by a sufficiently hyuuuge meteor that could harm all of mankind.
