The present state of our knowledge on extra-solar planets is reviewed. Although it is mainly limited to giants, their extraordinary diversity is impressive. A list is made of some information we are eager to get: (I) understanding the presence of hot and temperate jupiters, (II) knowing the abundance and size and distance distributions of terrestrial planets. The capabilities of theories to make predictions is considered and it is concluded that they are not presently very efficient because they depend upon unknown parameters. This stresses the importance of observations. Finally, the atmospheric composition and climate of terrestrial planets is discussed as well as the tools we have to investigate the ubiquity of life in the Universe, one of the most significant problem that Science can address.
