Scientists Have Underestimated The Likelihood Of City-Killing Asteroids Hitting Earth

Scientists Have Underestimated The Likelihood Of City-Killing Asteroids Hitting Earth

The chance of a city-killing asteroid striking Earth is higher than scientists previously believed, a non-profit group building an asteroid-hunting telescope said on Tuesday.

A global network that listens for nuclear weapons detonations detected 26 asteroids that exploded in Earth's atmosphere from 2000 to 2013, data collected by the Comprehensive Nuclear Test Ban Treaty Organization shows.

The explosions include the Feb. 15, 2013, impact over Chelyabinsk, Russia, which left more than 1,000 people injured by flying glass and debris.

"There is a popular misconception that asteroid impacts are extraordinarily rare ... that's incorrect," said former astronaut Ed Lu, who now heads the California-based B612 Foundation.

The foundation on Tuesday released a video visualization of the asteroid strikes in an attempt to raise public awareness of the threat.

Asteroids as small as about 131 feet (40 meters) — less than half the size of an American football field — have the potential to level a city, Lu told reporters on a conference call

"Picture a large apartment building — moving at Mach 50," Lu said.

Mach 50 is 50 times the speed of sound, or roughly 38,000 mph (61,250 kph).

NASA already has a program in place that tracks asteroids larger than 0.65 mile (1 km). An object of this size, roughly equivalent to a small mountain, would have global consequences if it struck Earth.

An asteroid about 6 miles (10 km) in diameter hit Earth some 65 million years ago, triggering climate changes that are believed to have caused the dinosaurs — and most other life on Earth at the time — to die off.

That’s logical, when there is more and more cities and larger populations, the targets for asteroids are larger.

I don’t think scientists underestimated anything.

They have been building NEAR EARTH OBSERVATORIES all over the planet for quite some time now.

You can go to SPACEWEATHER.COM and get the latest data on NEARs and even see their orbits.

Many countries have built huge underground ‘shelters’ just in case an asteroid were found to be headed right at Earth.

Maybe they spend more time preparing, and less time ‘informing’ the public, but... unprepared ?

Well I just attended “Craterfest” in lovely downtown Wetumpka, Al on April 19th. I hope since one has already hit in my neighborhood that it will be like lightening and won’t strike twice...lol

Here’s some info on our local crater:

Note where that one crashed.

I don’t think it’s by chance it crashed so far north. The worries are overblown.

There are far more, and greater, dangers than a meteorite hitting a city.

Savage invaders from the south invading our cities, is but one example.

Nationalized health insurance, the Environmental Protection Agency................ this list is nearly endless.

Before a city killing asteroid can kill a city, it has to hit it. In all of written history there have been a couple such asteroids, and they missed the cities.

Yawn.

Rain of Iron and Ice: The Very Real Threat of Comet and Asteroid Bombardment
Rain of Iron and Ice:
The Very Real Threat of
Comet and Asteroid Bombardment

by John S. Lewis
On November 27,1919, a meteorite fell into Lake Michigan near the Michigan shore. "Residents of Battle Creek, Kalamazoo, South Bend, Grand Haven, and other Western Michigan cities fled from their homes in panic, fearing an earthquake. Houses were shaken, the country was illuminated as by a bright sun's rays, so all-enveloping it was impossible to tell from which direction the flare came, the earth trembled for half a moment and then came a deep prolonged rumbling as of a terrific explosion." (p 159)

Most of the land area is in the northern hemisphere, and one entire s-hemisphere continent is basically uninhabitable (although I’ve seen some sentiment for making all the muzzies move there).

http://www.barringercrater.com/education/craterfacts.php

The crater is about 1 mile wide and 570 ft deep... About 50,000 years ago, a meteorite traveling about 20 km/s smashed into the Arizona desert. The explosion was equal to 2.5 megatons of TNT... The meteorite was made of nickel-iron and is estimated to have been about 45 meters (150 ft) across, weighing about 270,000 metric tons (300,000 tons).

http://news.nationalgeographic.com/news/2007/11/071107-russia-crater.html

On June 30, 1908, a ball of fire exploded about 6 miles (10 kilometers) above the ground in the sparsely populated region, scientists say. The blast released 15 megatons of energy—about a thousand times that of the atomic bomb dropped on Hiroshima—and flattened 770 square miles (2,000 square kilometers) of forest.

It's perfecting its aim. Not easy to hit a moving target from such a distance!
