Abstract: “Without turbulence - no planets - no Solar System - no life on Earth.” The solar system’s minor bodies, asteroids, trojans, comets and Kuiper belt objects, are leftover planetary building blocks called planetesimals. The largest of these planetesimals grew into planets through collisions and the accretion of large grains called pebbles. Despite their importance we still do not know where and when they were born in the solar nebula. Here I report on our numerical experiments in Comprehensive Project 2 connecting three stages of planetesimal formation 1.) the evolution of the dust size distribution in the turbulence of a circumstellar disk, 2.) concentration and diffusion of pebbles in geostrophic flow features as vortices and zonal flows and 3.) the gravitational collapse of pebble clouds into clusters of planetesimals. With our ongoing project we aim to calibrate the planetesimal formation process against observational and laboratory data for minor bodies in the Solar System, allowing to reconstruct the turbulence during the birth of the Solar System and connecting our home world to the diversity of exoplanets. *Pretalk starts at 1.00 PM*
