Episode 40: Keeping an eye on asteroids with Dr. Don Yeomans

Dr. Don Yeomans, head of JPL’s Near-Earth Object office until his recent retirement, stops by to talk asteroids on the show. He talks about how the field of asteroid discovery has changed over the decades. He also describes what happened when early data indicated that the asteroid Apophis had a small chance of hitting the Earth (spoiler alert: today, with more data, we know that Apophis will not hit the Earth).
