Earth races around the sun at 67,000 MPH in a solar system full of debris left over from its formation 4.6 billion years ago. We've had countless encounters with these remnants throughout our history, with devastating effects to life on the planet. In this episode we discuss the threat these objects pose to humanity, what we're doing to mitigate the risks, and the damage these objects can inflict upon the world if we're not successful in doing so.
