Super-Earths and sub-Neptunes are the most common planets discovered in our galaxy to date. I will present our latest understanding concerning their formation, atmospheric accretion, evolution and loss. I will show that we can constrain the core composition of these planets to terrestrial-type densities with a water fraction of at most 20%. I will discuss what these findings imply for the abundance and search of true Earth-analogs and I will conclude with new insights into the geophysics and geochemistry of extra-solar rocks.
