That's a bit of an overdramatic title, but it's true that the most efficient way for us to reduce the risk we face from asteroids that have a very small chance of hitting Earth in the future is to determine their orbits more precisely.

It was January of 2004 when the elegant curve of the Vichada first caught the attention of geologist Max Rocca of Buenos Aires. Could the course of the river have been shaped by the circular outlines of an impact crater? Rocca decided to find out.

In less than 24 hours, a newly discovered asteroid known as 2010 AL30 will be zipping past Earth at an altitude of approximately a third the Earth-Moon distance. There's no chance it'll hit us, but it's generating a lot of excitement in the community of amateur and professional near-Earth asteroid observers.

On Wednesday, September 29, Earth will dodge a cannonball: the Near-Earth Asteroid known as 4179 Toutatis will buzz by at a distance only four times the distance from the Earth to the Moon -- about one and a half million kilometers, or about a million miles. But, as the wisdom goes, "close" only counts in horseshoes and hand grenades; Toutatis' flyby will have no effect whatsoever on us.
