Endangered Planet

In most of these rocks "great coming on the earth" movies just nuke them or something like that. In real life what would be the real solution or do we simply hope for the best?

No, here, we just nuclear asteroid heading for us. Is this really an improvement? Does not look like it.

The technology is being developed to deflect asteroids, if necessary. All we really have to do is go into something and send it off track by a few hundred miles - it does not take much to miss, and he would not do much to move a track if we have seen fairly quickly.

And there are programs to monitor asteroids in the world in search of the next great toward us.

At present, we would be screwed. In the future, of course, even a conventional warhead could be enough to deflect a trajectory to avoid something striking the earth.

Yes, we can, and make them jump through thousands of pieces raining death and destruction across the planet Earth. Therefore, the solution favored today is to use "gravity tractors", taking advantage of the fact that in outer space without gravity, however small satellites can perform gravity on a meteor, and slightly out of its trajectory. The idea is to make this year before the impact, and we need only a very slight pull to throw him off track and miss the Earth.

Meteor? Why would you? The meteors are small.

Asteroids, on the other hand, are large. And I do not know if we have something big enough to distract one that is large enough to constitute a significant threat.

The good news is that the space is really, really big, and it is a rare event.

If a meteor nukes, we could be saved, or be killed.

It depends on the size of the meteorite. If it is a small meteor, and we blow apart with a nuclear weapon, small pieces can only burn in the atmosphere

But if it is large, instead of obtaining a large meteor we would get a thousand a semi-major

It would probably destroy life as we know

depends on the size. the probability of success is very low.

Reality is not a bruce willis movie life. and in real life, we would be screwed since all our resources have been requisitioned by the bush league.

As mentioned above meteors are small. If enough astroid headed this way ..... you understand that it is not necessary to really hit us.

Here is a good website that talks about NASA earth near objects.
Research is ongoing.

Your concern is whether there would he a ballistic missile or any obstacle to neutralize the large meteor (Asteroid) before it hits land.

You must understand one thing that is energy is not coming from nowhere, back to Newton's law. Energy is transferred in different form during the collision. If the missile capable of neutralizing an asteroid, the amount of kinetic energy is transferred into thermal energy is a disaster. This heat will eventually return to earth in radiant heat.

The missile is most effective to hit the asteroid at an angle and probably head, the intention is to divert the flow of meteor away from Earth in orbit around the sun.

Anything big enough to be a major threat is much too big for a nuke divide as in "Armageddon". In most cases, we should have years of warning, but perhaps enough time to gently push the rock on a slightly different orbit. However, the technology for this is that in the discussion stage.

More than an asteroid of the Earth, the greater chance we have of diverting its course with a nuclear weapon. The closer it gets to Earth, the more energy it will take to deflect. Unfortuanately, as far as he is, the harder it is to send a rocket to intercept it. If a.
