My Way News - NASA IDs 90 pct. of largest near-Earth asteroids
My Way News reports: "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."

Comment: I think it's that last 10% that could really ruin your day.
