Episode 315 - Asteroids, meteorites and the destruction of moons

It's easy to think of the solar system as a static object that's always been there. But by studying asteroids, meteorites and moons we can piece together the often violent and dramatic history of our solar system. From Earth being bombarded by water bearing asteroids, to moons being broken apart and reformed around Neptune. We even follow up on some of the great work done by JAXA and the Hyabusa 2 mission. This week we look at some of the latest research into our solar system by studying the smallest often overlooked pieces. References: Josep M.
