If a planet destroying asteroid were headed our way, would you want to know?

As a scientific mind and an individual who is curious, I would like to know. Then I could find a location to watch the impact with my family so I would know such a rare occurance and then die happily. Of course, an asteroid cannot destroy a planet unless it is planet-sized, and there are none left; an asteroid can only cause massive extinction events like the K-T impactor (aka "The Dinosaur Killer"), and probably cripple the human race. Watch "Deep Impact"; it's the most accurate movie made about such a thing thus far.

The truth is ...\nAn asteroid discovered just weeks ago has become the most threatening object yet detected in space. \nA preliminary orbit suggests that 2002 NT7 is on an impact course with Earth and could strike the planet on 1 February, 2019 - although the uncertainties are large. \n\nAstronomers have given the object a rating on the so-called Palermo technical scale of threat of 0.06, making NT7 the first object to be given a positive value. \n\nFrom its brightness, astronomers estimate it is about two kilometres wide, large enough to cause continent-wide devastation on Earth.

Ask the designer of the Solar System he probably know.

i dont think anyone really knows for sure. probably like thousands of millions of years. unless it gets hit by a ginormus asteroid and explodes into teeny tiny peices!! lol

yeh, a meteorit and a galaxy are coming to earth. Don't worry, they come only after 2 milion years...;))

we will be hit by an asteroid tomorrow. 1 billion people will burn instantly, the rest will slowly starve as the dust clouds block the sun.\n\nSo please save yourself from this pain and jump off some high building today.

How would we know? I am not gonna stay alove for a million years, neither will you. I don't mean to be arrogant, but honestly why should we care. I say live by the moment. Focus on what you are doing NOW. But if you really want an answer, I think now. You know what, it won't be the sun or a black hole that destroys us, it will be the human race, and maybe natural disasters. Look at the wars, we are killing eachother! In the past year earthquakes and tsunamis have outbroken wiping out even more of our civilizatiopn. We are only destroying ourselves.

Nah, probably not like this. Very probable that there's a planet with intelligent life though.

I'd want to witness the arrival of the first human life on earth. With all the theories of evolution, creation and so on, it would be nice know, once and for all, just how the hell we got here.

Not in our lifetime.  It takes 1,500 years for it to complete its eliptical orbit between our Sun and a dead sun outside our galaxy.  We have a better chance meeting helpful space visitors before planet X will return.

Yes, it is virtually certain that asteroids have hit earth. First of all, earlier in the history of the solar system there were probably many more asteroids than there are now, so the odds of a collision were greater. More recently a large asteroid impact is credited with having led to the extinction of the dinosaurs. Other planets and their moons show many craters, which provide evidence for asteroid impacts. On earth these are destroyed by weathering. The June 1997 issue of Sky and Telescope has an article on this subject in which they estimate that a very large asteroid impact occurs once every 100 million - 1 billion years (the earth is 4 billion years old), and a large asteroid impacts once every 1 - 100 million years.

hopefully there's another planet wherein we could banish you to

It seems very possible that asteroids seeded this planet with life. That might have not been as accidental as some people think.

wouldn't you like to know??

Well we are rather accustomed to the current orbit.  I personally would find life in either mercury's or pluto's orbit a tiny bit trying, and yes, probably life-shortening.
