Close Call Asteroid



"A newly discovered asteroid designated 2009 VA, which is only about 7 meters in size, passed about 2 Earth radii (14,000 km) from the Earth's surface Nov. 6 at around 16:30 EST. This is the third-closest known (non-impacting) Earth approach on record for a cataloged asteroid."

CAUTION: I would caution you about discussing this topic with your students. Be sure you are prepared for some of them reacting strongly to this! They seem quite grown-up at the middle-school level, but many still carry a child within and may get "creeped out" by this type of scenario.
