The landscapes of exoplanets are likely to be incredibly diverse: exoplanets come in a large range of sizes and masses, and therefore surface gravities. Atmospheres can be thick layers, or absent. The interior makeup of exoplanets is even harder to know, but the formation scenarios of the giant planets and the remains of planets found in white-dwarf atmospheres provide insights. All that knowledge, combined with information on the central stars and other exoplanets within a system, provides a view of past, present, and future environments. This chapter reviews sample exoplanets and the conditions on their surfaces.
