Weekly Reader News - Senior;10/13/2006, Vol. 85 Issue 6, p3
The article reports on the formation of a special task force by the International Astronomical Union to closely monitor asteroids hurtling through space toward Earth. Experts estimate that hundreds of comets and asteroids at least half-mile wide are spinning through the solar system. The task force is planning to develop a permanent warning system. Close encounters with asteroids help astronomers gain a better understanding of the origins of the solar system.
