Abstract

The next great goal for space exploration and discoveries is the discovery and characterization of planet systems about other stars. Spacecraft have visited all the planets of the Solar System except Pluto. The final step, a flyby or rendezvous with this interesting double planet is now being given serious consideration. What's next? Do some other stars have planets? And if so, are they like our Solar System planets? Are there any like the Earth?
