  • Super Earths, because we know so little about them. They are the most common planet type (based on census from Kepler and TESS), but our solar system doesn’t have one, so we have no idea what they are like. Models and simulations give a few possible compositions, resembling mini-Neptunes, or water worlds with thick oceans, or more like Earth. Maybe all are possible. Earth-like rocky super-earths may be more geologically active than Earth, due to stronger convection and thinner crust. If they orbit a K-type dwarf, they could be candidates for super-habitable planets, with conditions even better for life than Earth.
