Early next week, a large asteroid named 2004 BL86 will fly past the
Earth-Moon system. There's no danger of a collision, but NASA radars
will be monitoring the mountain-sized space rock as it passes by only
745,000 miles away. Amateur astronomers can watch the flyby, too.
Glowing like a 9th magnitude star, 2004 BL86 will be an easy target for
backyard telescopes on the night of closest approach, Jan. 26-27.
