UN's new asteroid monitoring group will defend Earth from killer space rocks

The United Nations is planning to set up an International Asteroid Warning Group that'll inform its member nations when asteroids are on collision course with Earth. When a dangerous rock is discovered, the UN's existing Committee on the Peaceful Uses of Outer Space will launch a mission to slam the asteroid off its trajectory.
