ASTEROID FLYBY: 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 (23:28 UT), the space rock will be 324,600 kilometers away. Nevertheless, professional astronomers are eagerly anticipating the flyby as the asteroid presents an exceptionally strong radar target. Even amateur astronomers might be able to photograph it during the hours around closest approach. Check http://spaceweather.com for observing tips and more information.
