(614433) 2009 KK is an Apollo near-Earth asteroid which was listed for several weeks in May and June 2009 on the Sentry Risk Table with a Torino Scale rating of 1.[3] There was a 1 in 10000 chance of an impact on 29 May 2022.[3] On 22 May 2009, it was listed as one of two near-earth objects assessed above Level 0 for potential impacts within 100 years, the other being 2007 VK184. As of 10 June 2009 it was downgraded to Level 0 as the cumulative Earth-impact probability was assessed as 7.9e-06 or 1 in 127,000.[4] On 17 June 2009, JPL removed 2009 KK from the list of potential Earth impactors.[5] It is now known that on 4 May 2022 the asteroid will be 0.475 astronomical unit|AU (71,100,000 km; 44,200,000 mi) from Earth.[2]

2194 passage

2009 KK may pass as close as 0.006 astronomical unit|AU (900,000 km; 560,000 mi) from Earth on 2194-Jun-02.[2] But the nominal solution shows the asteroid passing 0.038 AU (5,700,000 km; 3,500,000 mi) from Earth.[2]
