Part of the Asteroid Family?
Could the Chelyabinsk bolide have been part of a larger asteroid family? Some researchers seem to think so.

This event was nearly ten times as energetic as the Sulawesi, Indonesia fireball of 2009.” This article by Margaret Campbell-Brown, Associate Professor in the Department of Physics and […]Read more
Tunguska By the Numbers: An Infographic
The last major asteroid impact was in Tunguska, Russia, in 1908, where an asteroid destroyed an area larger than the Washington D.C. metropolitan area. More recently, on February 15, 2013, we witnessed the close fly-by (only 17,000 miles away) of Asteroid DA-14 and the real impact of a smaller asteroid over Chelyabinsk, Russia. “These events […]Read more
