Asteroid Apophis 2004MN4 will come within 29000 km/ 18000 mi of striking the Earth on April 13th, 2029 this asteroid will come inside the orbits of most of are major satellites. This asteriod is the size of 3 football fields and if it hits a 400km gravitational keyhole as it sling shots aroung us then it will return in 2036 for impact. check out the videos on my site.Astronomy and Pictures, See the damage that can happen.

First, what is the question? (this is Q&A)

Second, my understanding is the latest predictions are that it is highly improbable that it will hit in 2036 (Link (http://en.wikipedia.org/wiki/99942_Apophis)).


However there remained a possibility that during the 2029 close encounter with Earth, Apophis would pass through a gravitational keyhole, a precise region in space no more than about 600 meters across, that would set up a future impact on April 13, 2036. This possibility kept the asteroid at Level 1 on the Torino impact hazard scale until August 2006. It broke the record for the highest level on the Torino Scale, being, for only a short time, a level 2, before it was lowered.[5]

Additional observations of the trajectory of Apophis revealed the keyhole would likely be missed, and on August 5, 2006 Apophis was lowered to a Level 0 on the Torino Scale. As of October 19, 2006, the impact probability for April 13, 2036, was calculated as 1 in 45,000.

Never heard of it.

Oh, wait...

Sorry, readers. I don't have time to list them all.

'interstellaryeller'... You are of coarse correct. We are doomed.
Right,... now I have got that of my mind all I need to do is sell the house and children and go and do all those things I want to before the April date of impact... was that 2012, or 2029, or is it 2036...Hmmm....?
It is not wrong to concern your self with this 'what if' and 'when might' but it is not accepted as mainstream science. The facts determining the orbital path of these objects is a work in progress. Many keen astronomers are working on tracking just such objects in an effort to better understand the 'risk'.
At this point in time I can speak with some certainty. This well documented object does not present a negligible risk. And just to further allay your fears. Even if it were to be seen as such a risk. Then a simple nudge would deflect it. No worries!... The shuttle is ready. Day- ja- vous. ( that can't be right.)

Well, if it is a near miss in 2029, it'll be a terrific opportunity to give it a little nudge so that 7 years later (and for millennia to come) it won't be an issue.
