It's an Earth sandwich! What if we placed our Earth between our Solar System's two asteroid belts: the Main Asteroid Belt and the Kuiper Belt. How long would it be before one of these belts sent their asteroids hurtling toward Earth? And what kind of collisions could we see if these space rocks hit us?
