Abstract: Super-Earths/Sub-Neptunes are planets ~1--4 Earth radii and ~1--20 Earth masses, composed of solids and gas in proportions of 100:1 by mass. We describe how super-Earths/sub-Neptunes form: the assembly of their rocky cores, the accretion of their atmospheres, and the distribution of their orbits inside and outside of mean-motion resonances.
