Asteroids & Comets


With Mark Bailey

Explore the latest discoveries (of which there are several) involving these diminutive bodies of rock and ice. Why are these little rocks so important to our understanding of our Solar System? We will primarily focus on several recent spacecraft visits and several new and upcoming missions. We will also explore their makeup through the examination of meteorites, and what they can tell us about these objects. A not-so-soothing look at near Earth asteroids and their potential threats to us will be included.
