"2005 YU55, also written as 2005 YU55, is a potentially hazardous object[2] that is 400 meters in diameter."

"In February 2010 it was rated 1 on the Torino Scale. On 19 April 2010, highly accurate radar targeting by the Arecibo radio telescope reduced uncertainties about the orbit by 50 percent.[4] This improvement eliminated any possibility of an impact with the Earth for the next 100 years.[4] It was removed from the Sentry Risk Table on 22 April 2010.[5]"

So, wiki says the diameter is 400 feet, not 1500 and that any possibility of impact was eliminated in April of last year- the page at wiki was modifed last week--why the contradictory info?
