The 7-metre wide asteroid 2009 VA  passed about 2 Earth radii (14,000 km) from the Earth's surface at around 16:30 EST, 6th November, 2009.  This was the third-closest known (non-impacting) Earth approach on record for a catalogued asteroid.
The two closer approaches were by the 1-metre wide asteroid 2008 TS26, which passed within 6,150 km of the Earth's surface on the 9th October, 2008, and the 7-metre wide asteroid 2004 FU162 that passed within 6,535 km on the 31st March, 2004.
On average, objects the size of 2009 VA pass this close about twice per year and impact Earth about once every 5 years.
