(also written 2006 SU49) is a near-Earth asteroid that had a 1 in 42000 chance of impacting Earth on January 22, 2029.〔 By October 29, 2006, it was listed with a Torino Scale impact risk value of 0. It was removed from the Sentry Risk Table on November 23, 2006.〔 It is now known that on January 28, 2029, the asteroid will be from Earth.〔 It is a near-Earth asteroid that received minor attention in late September and early October 2006 because initial observations indicated a higher than usual probability that it would strike the Earth in 2029. However, the Near-Earth Object (NEO) Office at NASA's Jet Propulsion Laboratory (JPL) removed from its risk list as additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon through 2106. Similarly, NEODyS estimates show a zero impact probability through 2080. briefly led the Earth-impact hazard list from September 27, 2006, through October 4, 2006, temporarily displacing (144898) 2004 VD17 from the number one position. At the time, both held a Torino scale of level 1 and were the only asteroids to hold a Torino value greater than 0. Even though has an Earth MOID of , the orbit and future close approaches are well determined with an orbital uncertainty of 0.〔 was discovered on September 20, 2006, by the Spacewatch project at the University of Arizona. The object is estimated at 380 meters in diameter with a mass of about 7.3 kg.〔 == See also == * List of notable asteroids * Asteroid deflection strategies * Asteroid naming conventions 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「(292220) 2006 SU49」の詳細全文を読む スポンサード リンク
