    I recently read an article in the paper saying that Meteorite Aphosis may strike the earth in 2029, ending it. If it doesn't the next possible time is in 2036 with a higher chance of the strike taking place.

    Good news....

    The UN will organize a plan of action

    Bad News....

    Bruce Willis and his offshore rig team won't be in it!!! (Sorry Die hard fans!_

    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.

    Nasa has estimated that an impact from Apophis, which has an outside chance of hitting the Earth in 2036, would release more than 100,000 times the energy released in the nuclear blast over Hiroshima. Thousands of square kilometres would be directly affected by the blast but the whole of the Earth would see the effects of the dust released into the atmosphere.
    And, scientists insist, there is actually very little time left to decide.

    Man we are so dead!!!

    That's not really big enough to take us out completely. It might just make for a good house cleaning though.

    If it struck the earth, there would be massive nuclear blast much much higher than Hiroshisma. There could be dark skies for years and crops would be destroyed.

    Good news though: Scientist says that if aphosis did hit, then many parts of middle east would be buried under the sea.

    It might be the only possible solution to the Israel Palestine crisis.

    Would it cause a tsunami or any other far reaching effects?

    NASA is trying to keep this threat as low key as possible in order to avoid any mass panic!

    That article is dated Oct 31, 2005. Old news.

    Newer news:http://www.msnbc.msn.com/id/12859900
    Updated: 6:28 p.m. CT May 18, 2006
    After a fresh round of radar observations, astronomers said Thursday that the chances of a catastrophic asteroid impact in the year 2036 are lower than previously thought — and they're hoping the threat will be completely ruled out once more readings are made. ​


    Newest news: JPL reduced the risk to 1/45,000 after further observations of Apophis (October 19, 2006).

    With this reduced risk, there is little justification in terms of a cost-benefit analysis for doing something more than just taking more measurements.

    im sure if it smacked the ocean, our maps would change.

    If it smacked in the ocean... not a change unless it's larger then half a km

    Any explosive, conventional or otherwise will require atmospheric pressure around such a target as a 'Meteor'. Without atmospheric pressure any explosion will be less than effective. This means that for any attempt at taking a meteor out would require first a kind of 'Atmospheric painting' whereby a smaller rocket would be sent just to create a gas cloud around the target point, with a follow-up rocket closely behind it with the payload.

    There are a few other theoretical ways to deal with asteroids two, for instance the use of Radiological antenna arrays to create an alternate resonance of the meteor even to cause it to vibrate to pieces or just alter it's course by a couple of degrees. The problem however is the distance at which the antenna array would be effective considering the inverse square law.

    where there is a nuke there is a way, wouldn't a nuke make one hell of a blast if it first impacted and get a bid buried? Especialy when a second nuke is hours behind waiting to aim itself on the underlying materials
    then the gas for the second nuke can be the vaporised loose dust from the first blast.

    You don't need to actually "blow up" the object, just slightly change its course. A nuclear explosion near the surface of the asteroid would vaporize some of the asteroid's outer surface, which would change its trajectory.
