they say that if the asteroid in 2029 hits earth it will kill us but i have also seen and heard that the ateroid will just miss us and come back seven years later do you think this will happen?

No. There's a more likely chance that we'll blow ourselves up.

In December 2004, an astronomer calculated that an asteroid discovered that year (asteroid 2004 MN4) had a one chance in 45 of hitting Earth in 2029, and he went as far as predicting the date as a Friday the 13th (April).
This means that the probability of a miss was 97.8%
I went to the NASA orbit site, where they show the orbits of all known asteroids.
I looked for 2004 MN4 in the list of "Potentially Hazardous Asteroids" and did not find it there (maybe it was taken off the list as no-longer-dangerous)
Still, I entered 2004 MN4 in the search box and found out that it is called Apophis, asteroid number 99942. A smallish thing (still, over 300 metres across -- 1000 ft) .
I saw that the orbit of Apophis is such that it comes relatively "close" to Earth every 8 years. There are many such objects. In a system such as ours, these kinds of objects are either in relatively stable orbits or they have crashed long ago.
I went to the Wiki page: in summary,
There was concern in December 2004. Then it was found that it was going to miss Earth in 2029, but there was some possibility that it could pass at some exact distance from Earth, such that its orbit would be changed just enough for Apophis to crash into Earth in 2036.
More observations were made and, after a while, it was found that Apophis would not pass through the danger point (called the keyhole).
There is still a slight chance of collision in 2037 (2029 + 8) but that is now rated as "one chance in 12,300,000".
Apophis represents our biggest "scare" so far. And it is no longer a scare. However, it will pass closer to us than the orbit of the Moon (meaning: there will be lots of nervous people in the days just before the pass).
Because a lot is now known about its orbit and dates of passage (and because it could tell us a lot about how Earth's gravity could affect the orbit of asteroids), some people are suggesting that we should place some kind of beacon on it, so we can study its movement with even more accuracy.
Not a bad idea.

No. it rather is rather previous information. while the asteroid Apophis became first found, there became some concern it ought to hit the Earth, yet extra moderen findings teach that, at maximum, it has one probability in 40 5,000 of hitting the Earth in 2036, and none in any admire in 2029. AOL must be having a sluggish information day.

This asteroid was long ago downgraded to zero as a risk by the IAU (NASA has nothing to do with this). No scientists today believe that there is any chance it will hit in 2029 or any time in the foreseeable future. Only crazies and cranks are still talking about it.

It's possible it can happen as I heard and read too that plans are being formed for that in mind. As for the comment above "as usual the usa will save the world", in all honesty, the USA is a country that at least DOES something about it. Unless you can do something better, I suggest you keep quiet.

No i don't think it will... A LOT OF PEOPLE IN HISTOR Y HAVE PREDICTED THAT A METEOR WILL HIT EARTH AND GO ARMAGGEDON BUT IT HAS NEVER HAPPEND... that does not mean that i am unafraid at what might happen... i watched this Youtube vid about what would happen if i giant meteroite woud hit us....just go to YouTube and type in: Meteor hit Earth. It is freaky!

There's like a .02 percent chance that it'll hit us the first time around, and about a 3 percent chance it'll hit us when it comes back. But we're working on it.

I doubt it. We have to survive past 2012 first when we will line up directly with a black hole and polar reversal will take place on earth. This means that the North Pole will be changed into the South Pole. Scientifically this can only be explained by the fact that the earth will start rotating in the opposite direction, together with a huge disaster of unknown proportions.

well i dont know but if its headed to earth nasa and the russians will start planning on something to avoid it in 22 years technology will be more advanced so its not likely to hit but they are prepared

No, right now NASA is working on that. As usual the USA will save the world.
