2005 YU55, also written as 2005 YU55, is a potentially hazardous asteroid that is 400meters in diameter. It was discovered on 28 December 2005 by Robert S. McMillan at Steward Observatory, Kitt Peak. The 2011 approach is the closest known by an asteroid with an absolute magnitude this bright since 2010 XC15 (H = 21.4) approached within 0.5 lunar distances in 1976.
Impact risk assessment:
In February 2010 it was rated 1 on the Torino Scale, indicating that a pass near the Earth is predicted that poses no unusual level of danger. On 19 April 2010, highly accurate radar targeting by the Arecibo radio telescope reduced uncertainties about the orbit by 50 percent. This improvement eliminated any possibility of an impact with the Earth for the next 100 years. It was removed from the Sentry Risk Table on 22 April 2010.
On 8 November 2011 at 23:28 UT, the asteroid will safely pass w A lunar distance of 0.85 is also 0.00217 AU (325,000km; 202,000 mi). On 9 November 2011 at 07:13 UT, the asteroid will pass 0.00160 AU (239,000 km; 149,000 mi) from the moon. During the close approach, the asteroid should reach about apparent magnitude 11, and may be visible to expert observers using high-end binoculars with an objective lens of 80mm or larger. Since the gibbous moon will interfere with the viewing, amateur observers trying to visually locate the asteroid will want to use a telescope with an aperture of 6 inches (15 centimeters) or larger.
