Bright Asteroid Flyby
Source - Space Weather News for Jan. 21, 2015: http://spaceweather.com
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.
