Hoo-ray! From here. I'm so relieved!
Then again...there is still that missing ten-percent.... 
Now all I have to worry about are massive earthquakes, nuclear meltdowns, tidal waves, oceans rising, the gulf-stream shutting down, major oil spills, food shortages and a few other things. It's still nice to have at least one such end-of-the-world scenario crossed off my list.If you're worried about a killer asteroid wiping out Earth, NASA has some good news.
The space agency said Thursday it has identified more than 90 percent of giant near-Earth asteroids, including ones as big as the one thought to have killed the dinosaurs eons ago. None poses a danger to the planet in the next several centuries.
"We know now where most of them are and where most of them are going. That really has reduced our risk" of an impact, said Amy Mainzer of the NASA Jet Propulsion Laboratory.
