Asteroid 2005 YU55 Update

Pasadena CA (JPL) Nov 08, 2011
The last time a space rock as big as 2005 YU55 came as close to Earth was in 1976, although astronomers did not know about the flyby at the time. The next known approach of an asteroid this large will be in 2028.
NASA scientists will track asteroid 2005 YU55 from the agency's Deep Space Network at Goldstone, Calif. for at least four hours each day from Nov. 6 through Nov. 10. Radar observations from the Arecibo Planetary Radar Facility in Puerto Rico will begin on Nov. 8.
The space rock will make its closest approach to Earth on Nov. 8 at 3:28 p.m. PST. The trajectory of asteroid 2005 YU55 is well understood.
At the point of closest approach, it will be no closer than 201,700 miles (324,600 kilometers) or 0.85 the distance from the moon to Earth.
