with Dr, Michael Busch (SETI Institute) Near-Earth asteroids are a population of small bodies whose orbits around the Sun cross or come near our planet’s orbit.  They turn out to be unusual physical environments: essentially rubble piles. They represent a natural hazard we ignore at our peril, because some of these bodies have the potential to impact Earth.  Dr. Busch reviews the near-Earth asteroid population, programs to track and characterize such asteroids, and current efforts to address the danger of asteroid impacts.

Rubble Piles in the Sky: The Science, Exploration, and Danger of Near-Earth Asteroids

Listen to exciting, non-technical talks on some of the most interesting developments in astronomy and space science.  Founded in 1999, the Silicon Valley Astronomy Lectures are presented on six Wednesday evenings during each school year at Foothill College, in the heart of California's Silicon Valley. Speakers include a wide range of noted scientists, explaining astronomical developments in everyday language. The series is organized and moderated by Foothill's astronomy instructor emeritus Andrew Fraknoi and jointly sponsored by the Foothill College Physical Science, Math, and Engineering Division, the SETI Institute,  the Astronomical Society of the Pacific, and the University of California Observatories (including the Lick Observatory.)
