Oh, Oh, Astronomy cast episode 714 orbital resonance welcome toomy Cast or weekly facts-based journey through the Cosmos, where we help you

understand not only what we know, but how we know what we know.

I'm Fraser Kane, I'm the publisher of the universe today with me as always is Dr. Pamela Gay, a senior scientist for the Planetary

Science Institute and the Director of Cosmoquist. Hey Pamela, how you doing?
