Dust and Rubble (2004)  Here, I show the early Solar System — well, not necessarily our solar system. Gas and dust has lumped together to form asteroid-sized planetesimals, and these will then come together to form the larger bodies astronomers call planetoids. Soon, the planetoids will have grown to the size of true planets. This image will appear in the forthcoming book The Big Bang by Jared Pereira.
