Near Earth Objects (NEOs) have played a major role throughout Earth’s history. (Ask a dinosaur if you doubt it.) More than 15,000 have been discovered so far, but scientists suspect many more cross the path of our home planet. They may contain secrets about the origin of the solar system – but could also bring humanity’s doom. While we’ve learned far more about them in the last few years than was known in all of previous history, big mysteries remain. And we still haven’t figured out how to deflect objects that could take out a major city as effectively as a nuclear warhead.
The Planetary Society returns to KPCC In Person's Crawford Family Forum for another Planetary Radio Live hosted by Mat Kaplan. We’ll hear how the sky is being watched and explore the early thinking about how to protect Earth and civilization. There’s a lot of work under way, from spacecraft that visit these miniature worlds to the hundreds of amateur astronomers who help find and track them.
