The bodies of the solar system formed 4.6 Gyr ago in the protoplanetary disk around the young protosun. Starting with submicrometre-sized dust and ice grains, collisions and coalescence led to the formation of aggregates, planetesimals, and eventually planets. Comets are believed to be the kilometre-sized icy planetesimals that were not accreted into larger bodies and have survived until today. It is poorly understood how bodies manage to grow to sizes larger than about millimetre to decimetre because bouncing and fragmentation terminate growth well below kilometres. Streaming instability arising from the coupling between the gas and millimetre- to decimetre-sized dust aggregates via drag is a promising mechanism to bridge this gap. The ins...
