Arecibo saves us from another potentially hazardous asteroid

Posted by Emily Lakdawalla on 2010/04/29 02:04 CDT

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.

2010 AL30: Watch out for low-flying asteroids

Posted by Emily Lakdawalla on 2010/01/12 11:52 CST

Posted by Emily Lakdawalla on 2004/09/27 12:00 CDT

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.
