Dwarf Planet Ceres Thrills as a Dying Visitor Closes In

Ceres is the queen of the asteroid belt. Her first Earthly visitor is nearing its last days in spectacular style.

Planetary Society Chief Scientist Bruce Betts has a summer guide to the night sky, looks back in space exploration history and delivers another Random Space Fact. He and Mat Kaplan also have a new space trivia question for listeners.
