I know that if one of these asteroids hit our planet the devistation will be horrid!
But i just cant help but be awe struck by the sheer destruction they cause almost unimaginable!

I just wondered if anyone else on here likes watching these almost breath taking video's, and would like to talk about,
what would happen if such a thing was to come around and we new about it years in advance before the asteroids collision?

Anyway here is a link to a good impact video - Asteroid Impact

I think if it were harnessed for use that it would be an awesome weapon. It would be almost impossible for others to know that anyone had used it as a weapon also. It would be seen as an act of God or nature, depending on the perspective.

I never really looked at it as being used as a weapon! WOW that just puts it into a whole new perspective!
In trying to imagine the technology it would take to control such objects i feel that this will never happen atleast in many years to come!
But as far as using asteroids as a weapon is concerned it would work until someone leaked out the secret technology.

They are supposed to be working on tech now to change the trajectory of asteroids.
I think it is Russia and the USA doing it, but I do not recall at this moment.

I think you read this article The Asteroid Tractor
Astronauts propose a nuclear-powered spaceship to tow away space rocks bound for Earth

By David Kohn | January 2006

An asteroid as big as a stadium is heading toward Earth. The impact could obliterate an area the size of Delaware. What to do? The stock answer usually involves nuclear missiles, robotic impactors or some other aggressive technique. But such methods may well fall short. Even after the asteroid was blown up, large chunks could still strike Earth.
Now NASA astronauts Edward Lu and Stanley Love have come up with a much gentler solution. They argue that the killer asteroid could be eased off its collision course simply by applying gravity.

Their plan calls for an unmanned spacecraft called a "gravitational tractor" to hover near the asteroid for a period of months or years. The small gravitational force exerted on the asteroid by the vehicle—perhaps as little as a quarter of a pound—would be enough to nudge the rock into a slightly different orbit, averting a crack-up. "You just want to hang there and let the spacecraft gradually adjust the asteroid’s course," Love says.

For example, to deflect a 700-foot asteroid, the astronauts envision a 20-ton nuclear-powered spacecraft shaped like a pendulum, with the heaviest part closest to the asteroid. This arrangement will produce the greatest gravitational force and will also help keep the ship stable as it hovers next to the asteroid.p> But the first real-world test might involve a much bigger asteroid known as 99942 Apophis, which is between 1,000 and 1,300 feet long and weighs perhaps 50 million tons. There is a very small chance—from 1 in 5,000 to 1 in 10,000—that this massive rock will hit Earth in 2036. Love and Lu say that if a gravitational tractor were sent up before 2029, when the asteroid will make a close pass to Earth, the job would be relatively easy, requiring just a one-ton spacecraft to make the necessary small adjustment in Apophis’s trajectory. "It’s like changing the angle of a bank shot in pool," Love says. "A little change early on has a large effect down the line."

Not sure if this has been posted before.

Scientists are monitoring the progress of a 390-metre wide asteroid discovered last year that is potentially on a collision course with the planet, and are imploring governments to decide on a strategy for dealing with it.

There's always a list of a dozen or more large asteroids set to collide with Earth; as they continue to approach they're courses are continually reassesed and are usually no longer deemed a threat.

I predict the same will happen with this one, it's nothing new. But then, you never know...

I recently watched a show that aired on MSNBC recently called: Countdown to Doomsday
It originally aired early 2006.
It is about what could cause Doomsday on Planet Earth, can we prevent it and what about the future?
It went over the 10 threats, and 10 solutions

It started with Volcanoes as the #10 threat..
The #1 threat was Deep Impact and it mentions the asteroid "Apophis"

I uploaded the video bit here:

Circle your calendar. April 13th, 2036 could be a really, really bad day on planet Earth.

A group of astronauts and engineers warns that an asteroid may pass uncomfortably close to Earth that day. The chances it will actually hit are just one in 45,000, but even at those odds, the scientists warn, the United Nations should consider a response
The scientists met this past weekend in San Francisco to discuss the potential threats asteroids pose to the Earth and what can be done to prevent a possible collision.

Most feared is Apophis, a large asteroid that will pass within 10,000 miles of Earth around 2029 and even closer in 2036.

Dr. Dan Barry, a retired astronaut, told ABC News, "Even if the probability is low of an asteroid hitting Earth, if it has the potential to have a significant impact, then it has to be looked at. It is the absolutely responsible thing to do. In fact, it would be irresponsible not to do so."

Barry said more research is needed so that when a potentially dangerous asteroid is found, there is a plan in place. He said it is therefore important to start the search for asteroids now, to allow enough time to effectively deal with them.


Scientists believe that if advance warnings of dangerous asteroids like Apophis can be made decades in advance, there will be enough time to try and knock them off course.

Nobody knows for sure what it would take to push a massive asteroid off its course, but the theoretical possibilities include detonating weapons on an asteroid's surface or using gravitational pull to alter a possible collision course.

But it could also break an asteroid into many pieces, all still headed toward Earth.

There have been several intersting posts on this asteroid and the potential threat so I have merged them into one topic.
