An asteroid estimated to be less than 200 feet across, flew past Earth on Monday. Dubbed 2008 DD45, the space rock (pictured in the red circle) was at an altitude just twice the distance of some communications satellites. For more info, and a video of the asteroid's journey, visit New Scientist(1).
Second hour guest, astronomer Phil Plait(2) commented on the near miss asteroid. Such small asteroids are tremendously faint and difficult to see coming, yet they serve as a wake-up call to develop technology to push them out of the way should they be on a collision course, he said. Plait also announced that he is now the president of JREF(3) (James Randi Educational Foundation), which seeks to "expose pseudoscientific frauds."
