2009 VA is an asteroid that came within 14,000 kilometres (8,700 mi) of Earth on 6 November 2009 making it the third closest non-impacting approach of a cataloged asteroid.[2]
With a diameter of only 7 metres (23 ft), scientists think that even if it had been on a direct collision course with Earth, it would have likely burned up in the atmosphere.[3] The space rock made its pass by Earth just fifteen hours after its discovery.[4]
The asteroid was first discovered by the Catalina Sky Survey at the University of Arizona. It was determined that the object would make a pass well within the orbit of the Moon, but would not strike Earth. The object passed so close to Earth that its orbit was modified by Earth's gravity.[4]
