Mark your calendars for an impressive and upcoming flyby of an asteroid thatís one of the larger potentially perilous space rocks in the heavens Ė in terms of smacking the Earth in the future.
Itís the case of asteroid 2005 YU55, a round mini-world that is about 1,300 feet (400 meters) in diameter. In early November, this asteroid will approach Earth within a scant 0.85 lunar distances.

But late in the day (Universal Time) on Nov. 8, the solar elongation will grow sufficiently to see it. Early on Nov. 9, the asteroid could reach about 11th magnitude for several hours before it fades as its distance rapidly increases, Benner explained.
