Watch Mini-Asteroid 2005 YU55 Buzz Earth « AstroNews

Earth is about to be visited by the largest close-approaching asteroid on record. Known as 2005 YU55, it is about a quarter mile (400 m) across, round, and quite dark. When it comes closest to us, at 6:28 p.m. EST (23:28 Universal Time) on November 8th, it will be 198,000 miles (319,000 km) from Earth’s surface — closer than the Moon’s orbit. Professional astronomers around the world will closely follow the asteroid as it glides across the sky.

Weather permitting, backyard skywatchers also have a chance to spot this interloper. A few hours after passing closest to us, it will peak in brightness at magnitude 11.1, roughly 100 times fainter than the limit of human vision. “the good news,” says Alan MacRobert of Sky & Telescopemagazine, “is that you should be able to spot the asteroid with your telescope if it has an aperture of at least 6 to 8 inches.”
