We owe a lot to our moon. Beautiful moonlit walks, higher tides, and regular seasons – all are made possible by our little rocky friend. But what would happen if we picked up a second moon?

Thanks to Dr. Neil Comins at the University of Maine for his orbital mechanics expertise and help with this episode!
