Russia Meteor Renews Focus on Asteroid Threats
A week after a meteor exploded over Russia on the same day that an asteroid swung closely past Earth, experts discuss how the potential threats posed by near-Earth objects should be addressed. Astronomers Donald Yeomans and John Tonry weigh in on how to keep the planet safe.
John Tonry is a professor and project leader of the Asteroid Terrestrial-Impact Last Alert System (ATLAS) at the Institute for Astronomy at the University of Hawaii in Honolulu, Hawaii.
Donald Yeomans is author of Near-Earth Objects: Finding Them Before They Find Us (Princeton University Press, 2013); manager of NASA’s Near-Earth Object Program Office; and senior research scientist and supervisor of the Solar System Dynamics Group at the Jet Propulsion Laboratory in Pasadena, California.
