Not worth worrying about for now, and if we ever do have to worry about it we have more than enough years to do something about it. Its already known that on its current trajectory it will miss in 2013. its next pass in 2020 will be to quote

Impact Probability: 1.2e-05



0.001200000% chance of Earth impact
or
1 in 83,000 chance
or 99.99880000% chance the asteroid will miss the Earth

Forget about 2012 DA14; if the Bad Astronomer is right, we need to be a little wary of 2011 AG5:

When AG5 passes us in February 2023, the Earth’s gravity will bend its orbit a little bit, changing the path the rock takes. If it passes close to the Earth the orbit changes a lot; if it’s too far the orbit changes only a little. But if AG5 passes us at just the right distance, the orbit will change just the right amount to put it on a collision course with Earth. This region of space is called a “keyhole”, and in this case, should AG5 slip through it, it will hit us 17 years later, in 2040. That collision, though not global in scope, would be catastrophic: equal to about a 100 megaton explosion, twice that of the largest nuclear weapon ever detonated.

The problem is, we don’t know the orbit of AG5 well enough to know if it will travel through the keyhole or not. ...

The experts say... 'there is nothing wrong with getting your affairs in order..':eek:

If I did collide with us would it be similar to The tunguska one or bigger? just tryin to work out how serious it would be. hopefully they're calculations are extremely accurate and it will miss us.Is our luck running out it's been over 100 years since tunguska.

That's always good advice, you could walk out in front of a bus in the morning. Goes for anything really.


Besides who are these "experts". Anyone can make up "experts" about anything especially the media with their sources and experts whom they never name or directly quote in context.

A 150-foot asteroid called 2012 DA14 will pass so close to Earth next year it will fly UNDER man-made satellites orbiting our planet. This body is a good bit bigger than other recent near-miss objects! Nasa's Impact Risk report said that the odds of the space rock actually hitting Earth are very low indeed - but on 2013 February 15 it will pass just 17,000 miles from Earth, just a bit more than twice the Earth's diameter!

If an asteroid of that size hit our our planet, it would cause an explosion similar to a major nuclear blast. Astronomers from the Observatory Astronómico de La Sagra in Spain spotted 2012 DA14 in late February and its orbit has been calculated to be very similar to Earth’s.

17,000 miles is much closer than many of our own orbiting satellites. This is believed to be the closest pass of a reasonable-sized asteroid ever seen before the actual pass itself.

In astronomical terms, 17,000 miles is pretty close, but in practical terms it’s a clear miss. After next year, 2012 DA14’s closest brush with Earth will come in 2020, but even then the odds of an impact will be less than the chance of being hit by lightning in your lifetime – 1 in 100,000.

So, Lotto ticket anyone?

LOL at painting it

They tried the same approach with icebergs, carbon black to get them to melt in sunlight. when it melts it washes off the colouring.

So I'd say it would only work if there are no more volatiles.

Sticking a solar sail on it would be cool.

60m ?

IIRC all the gold ever mined is about 20m
