From February to May 2006 it was listed with a Torino Scale impact risk value of 2, only the second asteroid in risk-monitoring history to be rated above value 1. The Torino rating was lowered to 1 after additional observations on May 20, 2006, and finally dropped to 0 on October 17, 2006. It was removed from the Sentry Risk Table on 14 February 2008.As of January 4, 2008, the Sentry Risk Table assigned 2004 VD17 a Torino value of 0 and an impact probability of 1 in 58.8 million for May 4, 2102. This value was far below the background impact rate of objects this size.2004 VD17 was discovered on November 7, 2004, by the NASA-funded LINEAR asteroid survey. The object is estimated by NASA's Near Earth Object Program Office to be 580 meters in diameter with an approximate mass of 2.6×1011 kg.It will pass 0.02 AU (3,000,000 km; 1,900,000 mi) from the Earth on May 1, 2032, allowing a refinement to the orbit.Being ~580 meters in diameter, if 2004 VD17 were to impact land, it would produce a crater about 10 kilometres wide and an earthquake of magnitude 7.4."@en }
