Small asteroid detected 4 days after passing as close as satellites | EarthSky.org

Back in the 80s I wrote a sci-fi novel about an asteroid collision.  That was before they’d proven the Alvarez Theory regarding the extinction of the dinosaurs.  Shortly after that, the movies “Armageddon” and “Deep Impact” came out.  After the close call in Russia, people are starting to realize this, indeed, could happen.

On March 15, astronomers detected an asteroid that had passed closest to Earth on March 11, sweeping in at about the distance of our geostationary satellites.
