Starship Asterisk*

Just found this. any updates on this Asteroid?

Although scientists have basically cleared us from any danger from asteroid 2002 NT7, which originally had been reported as an impact hazard for the year 2019, a newer space rock has been spotted, which may pose a threat even sooner.

At around 1.2 km in width, 2003 QQ47 is substantially smaller than 2002 NT7 (2km), but has been called "an event meriting careful monitoring" by astronomers. If an impact does occur, it could be on March 21, 2014.

Think I,ll start digging a big hole in my back yard.

They also give an update that said "No danger" but im sure they keep an eye on it. No need to dig.

"Update:
Once again, the planet can breathe a sigh of relief. After making further observations of asteroid 2003 QQ47, astronomers now say there is no threat from this rock. It has been downgraded to a zero (0) on the Torin scale, which says, "The likelihood of a collision is zero, or well below the chance that a random object of the same size will strike the Earth within the next few decades. This designation also applies to any small object that, in the event of a collision, is unlikely to reach the Earth's surface intact."
While this particular asteroid appears to not be a threat to Earth at this time, the Near Earth Object Program and other agencies continue to monitor space for other threats. After all, it is a big universe, and there are a lot of asteroids and comets out there."

from the url: "... If it does strike Earth, the impact could have the effect of over 20 million Hiroshima style atomic bombs. As Billy Bob Thornton says in Armageddon, “It's what we call a Global Killer....the end of mankind. Half the world will be incinerated by the heat blast.....the rest will freeze to death in a nuclear winter. Basically, the worst part of the Bible!”

Another example of corrupting the bible. In the bible, until the universe itself explodes and reforms, the worst acts of destruction always leave a remnant of mankind, the remnant including nations.

What damage can it make to Earth?

No damage at all since it wont hit. But if an unknown one do hit with the same sise then it wil be bad. Man kind will probably have to start all over again. But it wont be exterminate. I think.

A close flyby will shake the planet in more ways than one.

This would be dependant on the size and density (relative gravity) of the body that is passing by. If it is large enough, like say Enceladus and passed at a distance relative to the Moon it would have little effect (certainly less than the Moons influence is currently). Passing closer than the lunar orbit would have a greater effect.
An object like Hyperion due to its vastly decreased density, would have a far lesser effect by passing even twice as close as Enceladus.
So there are many relative dependencies to consider when predicting an effect of a passing body.
Most asteroids (excluding Ceres, Vesta, don't have the gravity to cause disturbances if they were to pass us by. Only if they hit us.

The asteroids under discussion are in the several kilometer diameter range. Bodies like that could pass close enough to skim the top of the atmosphere and have absolutely no effect besides a nice light show.

Mankind attempted that with the stone age in the 60s and 70s .. that effort failed, but what an afterglow.
