Supposedly, on January 29 2008, this asteroid (TU24) will come within 500,000km with Earth. There's a few youtube videos, and a small forum with information about it, but I don't know how reliable those sources are. They do supply a link to the NASA website where they have an interactive demonstration of the orbit of TU24, and Earth intersecting on January 29th.

Here's the link incase anyone is interested: http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2007%20TU24;orb=1
To see the orbits better, change the center of the diagram from "Sun" to either "Earth" or "Asteroid/Comet"

The only thing about all this is that it hasn't been mentioned in the news at all. I've seen that one that was going to hit Mars a few times in the news, but not this one.

So, I'm just wondering if this could possibly hit us, or if not, what would be the concequences of it coming within 500,000km? And is this even true at all? Or is it one big hoax?

OK, the object your describe is an Apollo asteroid, a class of asteroids whose orbits come farily close to Earth's and intersect it at some point. These objects are of interest, as they may one day impact this planet, with potentially devastating consequences up to and including the extinction of the human race.

The asteroid in question is a small one, only a few hundred feet across, and will pass about 0.00125 AU (about 70,000 miles) from Earth on 1-28-08 at closest approach. This is not immediately worrisome, but it bears watching, as it may come back and impact the planet at a later date.

The one nearing Mars has been determined to be no threat to it and will NOT impact the planet.

I don't think that this asteroid's gonna get close enough to do this, but an asteroid coming very close to Earth may damage a satellite and disrupt communications (or whatever the satellite is used for) here on Earth, but other than that, I don't think it would have much of an impact

FYI, at the direction of the President and Congress, NASA maintains a database of all currently known Apollo objects and has the singular goal of finding and cataloguing all that may exist (estimated to be somewhere around a thousand or so) , for the purpose of providing advance warning of an impending impact event, with the aim of finding ways to divert the incoming potential impactor. The odds in any given year of a sizeable asteroid or other object hitting Earth are small, but such impacts have happened in the past and WILL happen again in the future. Goggle "Earthwatch" and "Apollo Objects" for more info. The NASA site is accurate.

I read a sci fi writer postulaing that a large meteor strike on mars might in some way or another help increase the surface tempeature of Mars. I n the long run that might be useful to humanity
