(144898) 2004 VD17 (provisional designation 2004 VD17) is a sub-kilometer asteroid, classified as near-Earth object of the Apollo group once thought to have a low probability of impacting Earth on 4 May 2102. It reached a Torino Scale rating of 2 and a Palermo scale rating of −0.25 (an impact hazard of about 56% of the background level). With an observation arc of 17 years it is known that closest Earth approach will occur two days earlier on 2 May 2102 at a distance of about 5.5 million km.
