Actually, astronomers cannot say that far in advance when or even if it will happen.
There are so many unpredictable factors involved over such extended periods of time, that the best we could do is wait until a few years before it happened to see the course of its orbit.
About a year before the comet hit Jupiter in 1994, it was predicted in advance, but even a year before, they couldn't fully determine where or exactly when. Watching it move during the year made the computations more accurate as the time approached.
The gravity of the Earth is less than half the gravity of Jupiter, so that makes an event that far into the future very much more uncertain.
The closer the event gets, the greater our certainty of its orbit and the more certain we can be about the prediction.
Even if it was destined to happen, IF we still exist in that year, we'll probably have the technology to deal with it.
All we would have to do is send a device to attach itself to the asteroid and give it a tiny push of merely a few inches long enough in advance and its long-term orbit would be so greatly effected to the extent that it would miss us completely. That's the simplest solution, even better, less expensive and more effective than using a nuke to divert it. The nations of the world would gladly cooperate to save the planet and share the expense of dealing with it if such an event were predicted with certainty.
In that distant future year we would probably have the technology to know at least far enough in advance to avert any likely impact, so you needn't worry too much about your great, great, great, great, great, great, great, great, great, great, great grandchildren getting hit on the head by it.
Right now, a bigger worry is an uncharted asteroid (and there are many) falling from a daylight sky so we couldn't see it at all in the glare of the sun until it was too late. That has even greater probability than the event about which you are concerned.
As for the Mayan prediction for 21 December 2012, based on historic considerations, I wouldn't worry much about that either.
The 'end of the world' has been predicted by so many religions and so many, many hundreds of times over several thousands of years without even coming close, that a valid question to ask would be:
Why should the Mayan prediction be any more likely than the multiple hundreds of other such predictions that all failed? In other words, what makes their prediction any more special than all the others that we should take it any more seriously?
How many times would listen to somone who cried "wolf, wolf", and no wolf appeared, before you stopped taking him seriously?
So, my advice would be:
Be afraid ... Be VERY afraid ... but not today.

I dont worry, cuz
1) I will be dead by then
2) There is a less than 1% chance that it will hit Earth
3) We have plenty of time to stop that chunk of matter from hitting Earth if it really will be.
Anyway you said Myans or Aztecs predicted 2012 to be the end of the world, the end can be caused by other reasons, or perhaps an asteroid hitting Earth before we even found it.

Occasionally a "Near Earth Object" is found who's calculated orbit seems to put it on a collision coars with Earth. The problem is, orbit calculations aren't perfect and can only give an approximation as to where the object might be at a particular date. The farther away that date is, the higher the degree of inaccuracy in the calculation. Many things can slightly change or alter the path of an object in space such that years down the line it's hardly where it was predicted to be. This can be something as slight as one side exposed to warming sunlight more than the other, or as large as a collision with another object.
I do not believe it can be said with certainty that this object will hit the Earth. The estimated orbit only says that decent probability of coming uncomfortably close to Earth. It could end up that it passes at a distance farther than the moon, however.

astronomical predictions that far ahead are not very accurate, because an asteroid is a very minute object in space and it's very very far away at this point. its orbit/course hasn't probably been studied for a long time. if they gave a closer date like within the next five years then I'd worry.

Even if that is true, don't you think the people who live here might be able to come up with a plan of action sometime in the next 870 years?

Ok, lets go with March 16, 2880. I am absolutely certain that this is the date. If it isn't, sue me the day after!

it said there is a one in 300 probablity that the asteroid wil hit thre earthin 2880.
Hopefully, humanity will have survived
if humans still survive by then, they will have better technology to deal with the situation
If we DON'T survive as a species until 2880, moot point.

the actual end of the world will happen when an asteroid hits earth on aug 13th 2029. the asteroid is coming so close, it will actually be under one of our satellites.
