Meteorite Identification and Impact Events

Charlie and Kirby explore the world of near-Earth objects (NEOS) including asteroids, comets, and meteoroids. They discuss their experiences in Wisconsin observing the night sky and clarify the differences between these space objects. The video includes a visit to Arizona for meteorite hunting with Jeff and a tour of the Behringer Crater, highlighting the impact events that shaped Earth's history. The episode concludes with a recap of the key learnings and a teaser for future projects.
