(391211) 2006 HZ51 is an 800 meter in diameter asteroid discovered on 27 April 2006 by the Catalina Sky Survey that with a 1.1 day observation arc was thought to have a 1 in 6 million chance of hitting Earth on 21 June 2008. Further refinement of the orbit quickly eliminated the risk. The preliminary orbit solution was at first thought to have a period of 7 years and a perihelion of ~1.1 AU. [MPEC 2006-H58, 28 April 2006, 2-day orbit].
