During the last thirty years over 6000 “exoplanets” have been discovered in distant solar systems. There are planets completing a revolution around their mother star in less than one day, as well as planets orbiting two or even three stars or moving on trajectories so eccentric as to resemble comets. Some of them are freezing cold, some are so hot that their surface is molten. But beyond that our knowledge falters: What are they made of? How did they form? What’s the weather like there? Are they habitable?
