Asteroids and Trojans. Part 1: Introduction to asteroids and setting the scene. A look at the early formation of our Solar system and how that in turn relates to the general conditions of how and where the asteroids formed within our Solar system. https://youtu.be/Il_DM-_Sw0g

Asteroids and Trojans. Part 2: Kirkwood gap and the density and distribution of the asteroids. A look at the difference between the portrayal of an asteroid field in films and the reality of the one in our Solar system. The asteroids are widely scattered and even occur in distinct bands creating the Kirkwood gap due to the synchronisation of the orbits of the asteroids and Jupiter. https://youtu.be/ibXLAewSTCs

Asteroids and Trojans. Part 3: Asteroid composition and the Lagrange point. Looking at the three major asteroid types, Metallic, Carbon and Silicon and how the distribution of the Trojan and Greek asteroids around Jupiter relates to the Lagrange point and the three body problem. https://youtu.be/QUEJYsGNRWE
