Near-Earth objects are asteroids or comets whose orbit intersects Earth's and which may pose a collision danger. KSJD's Tom Yoder talks with Dr. Ray Williamson, an astronomer and the former director of the Secure World Foundation, about what scientists are doing to better detect which near-Earth objects may collide with our planet, what danger these objects pose to us, and how we may be able to keep these ever-present threats from hitting Earth.
