Asteroid 2007 TU24 flies past Earth this week at a distance of only 334,000 miles (1.4 lunar distances). There is no danger of a collision, but it will be close enough for amateur astronomers to photograph through mid-sized telescopes. At closest approach on Jan. 29th, the asteroid will glide through the constellations Andromeda and Cassiopeia glowing like a 10th magnitude star.
