The huge asteroid 2005 YU55 was small and dim in the sky during its close Earth approach yesterday (Nov. 8). At 1,300 feet (400 meters) wide, 2005 YU55 is about the size of a city block. It came within 201,700 miles (324,600 kilometers) of Earth Tuesday at 6:28
Discovered nearly six years ago by Robert McMillan at Steward Observatory’s Spacewatch Telescope in Arizona, 2005 YU55 has been this way before. In April 2010 it passed close enough for detailed radar probing by the giant radio dish at Arecibo, Puerto Rico. It
NASA radars are monitoring 2005 YU55, an asteroid the size of an aircraft carrier, as it heads for a Nov. 8th flyby of the Earth-Moon system. There is no danger to our planet. At closest approach on Tuesday at 3:28 pm PST, the 400m-wide space rock will be 324,600
Ok, people. We survived flyby of most popular "doomsday" Comet Elenin, now we facing another potential threat. Scientists assure us that we have nothing to worry about. Asteroid 2005 YU55 is the third close fly-by of a large asteroid to the Earth this year.
Comet Elenin (C/2010 X1), widely known for inaccurate reports of its threat to Earth, appears to be breaking apart. Observations by amateur astronomer Michael Mattiazzo of Castlemaine, Australia show a rapid dimming and elongation of the comet's nucleus akin to
Near-Earth asteroid 2005 YU55 will pass within 0.85 lunar distances from the Earth on November 8, 2011. The upcoming close approach by this relatively large 400 meter-sized, C-type asteroid presents an excellent opportunity for synergistic ground-based observations
