Summary: This week’s guest is Dr Paul Chodas, who directs JPL’s Center for Near-Earth Object Studies. He explains how predicting where an asteroid is going can get complicated when the asteroid gets close to a planet. He also talks about an app that lets you explore how a hypothetical asteroid could be deflected.
