Asteroid will have a near miss in 2029

btw, how do they know for certain it won't strike
the earth if it will approach within 25,000 miles?
It says that the object will be so near, observers
will be able to sight it with the naked eye...that's close!

Basically,The same way they can calculate the trajectory of a space
probe, and get it to where they want it to be.

but no cigar. :-)

For a couple of weeks, they actually did believe it might hit Earth. The
highest probability in the process of calculating it's trajectory was
1/37th - that's about the chance of throwing the same number twice in a
row with a die!

But, as time goes by, the trajectory calculation gets more and more
accurate, so now it can be said that it won't hit earth for certain.

PS: Oh, by the way, it's a "near hit", not a "near miss". A collision is
a near miss ("look, the two planes nearly missed!" - "yeah, but not
quite!").

42,000 km?

excellent! does anyone have the means to capture it into earth orbit?

opportunities like this are literally once-in-a-lifetime!

please tell me a its a nickel iron.....

It was on such a captured asteroid that the first Warp field test was
conducted! ;-)

Hi.I wonder if it is possible that the asteroid during that long period
get's some "influence" from some other unknown small object that we don't
see and that his trajectory would not be that safe as predicted?

There's always a degree of uncertainty, but a small object is
unlikely to have other than a small effect, especially over a short
time period.

Well sure. The aerodynamics of porcine animals aren't well established.
We could all be dead of bird flu, too. Or eaten by the giant space goat.
