What Goes Around Comes Around

Objects in our solar system can take pretty torturous paths to get from point A to point B. Nature can scramble the orbits of asteroids, and people can make satellite orbits scramble in just the right way to go from one orbit to another. Strange, Charm, and Top explore the ways orbits change and a new research report that says that most of the asteroids in the inner part of the asteroid belt may be the debris of just five primordial protoplanets that got smashed to smithereens billions of years ago. That's why the new name for asteroids is going to be "smithereens". Plus: nerd news and spaceflight history trivia!
