The Earth has had a near miss this week when a huge asteroid whizzed past, less than 50,000 miles away.

The asteroid - about the size of a 10-storey building - flew past the Earth at roughly twice the distance of the highest Earth-orbiting satellites, according to website space.com.

It is similar in size to a rock that exploded above Siberia in 1908, flattening 80 million trees across an 800 square mile area.

The impact had the force of a thousand atomic bombs, astronomers say.

Asteroid 2009 DD45 was closest to the earth on Monday at around 8.30am, at just under 45,000 miles above the surface of the planet.

Astronomers knew it was coming after it was spotted last Saturday as a faint dot showing up in pictures at the Siding Spring Observatory in Australia.

There was never any risk of collision, experts said, but anything flying within 50,000 miles of the Earth is taken very seriously.

The closest listed "flyby" to Earth by an asteroid happened in March 2004 when a small one - 2004 FU162 - measuring about 20 feet across came within about 4,000 miles of the earth.

Asteroids are rocks ranging in size from a few feet to several miles in diameter.

Most of them orbit the sun in the asteroid belt between Mars and Jupiter."

If it hit us we wouldn't be worrying about some stupid stock market anymore.

Why? What could we do to stop it? Other than send Bruce Willis into space.

Wouldn't work if we learned about it last saturday.

For what it's worth I have watched the Discovery Channel on this, and scientists don't seem too worried. They seem to think they could send something into space and use gravity to alter the path ever so slightly so it wouldn't hit us. They kind of made fun of the nuclear bomb thing....

all this hippy ass "use gravity to slowly change the course of the asteroid" is a bunch of garbage. detonate a damn nuke on it's surface to deflect the thing. if the first nuke doesn't work, use another.

I wonder if we'll do anything about the Friday 13th 2029 asteriod...

"The asteroid is about 320 meters wide. "That's big enough to punch through Earth's atmosphere," devastating a region the size of, say, Texas, if it hit land, or causing widespread tsunamis if it hit ocean, says Chodas...

On April 13, 2029, asteroid 2004 MN4 will fly past Earth only 18,600 miles (30,000 km) above the ground. For comparison, geosynchronous satellites orbit at 22,300 miles (36,000 km)....

"NASA initially estimated the energy that Apophis would have released if it struck Earth as the equivalent of 1,480 megatons of TNT. A later, more refined NASA estimate was 880 megatons.[2] The impacts which created the Barringer Crater or caused the Tunguska event are estimated to be in the 3-10 megaton range[16] The 1883 eruption of Krakatoa was the equivalent of roughly 200 megatons.

"A near miss is an unplanned event that did not result in injury, illness, or damage - but had the potential to do so. Only a fortunate break in the chain of events prevented an injury, fatality or damage. Although human error is commonly an initiating event, a faulty process or system invariably permits or compounds the harm, and should be the focus of improvement. Other familiar terms for these events is a "close call", or in the case of moving objects, "near collision". Indeed, the term "near collision" is less contradictory in nature than "near miss", since a "near miss" would be a hit that almost missed (a glancing blow) versus a miss that almost hit."

^^^ if you can google that, you can google your answer.

Quote :
"As a result, the panel said it would be necessary to launch missions to deflect or destroy asteroids that have only a one in 10, or even a one in 100, risk of hitting our planet.

"Over the next 10 to 15 years, the process of discovering asteroids will likely identify dozens of new objects threatening enough that they will require proactive decisions by the United Nations," the report added.

In addition, such missions will have to be launched well ahead of a predicted impact, so that slight deflections by spaceships can induce major changes in an asteroid's paths years later.

Hopefully we will at least rename the thing. Saying asteroid 2004 MN4 all the time would really try everyone's patience.

^And then they'd end up pushing one into our path that otherwise wouldn't have hit us because half their work was in metric and the other half wasn't.
