Most people, including most people who are in favor of human expansion beyond the Earth, don't realize just how rich is the Solar System. They tend to look only at the major terrestrial planets and assume that the only place into which we can expand without interstellar travel is Mars, because there are only three such planets in our Solar System aside from our own Terra, and Mars is the only one of these major terrestrial planet not to be far too hot (Mercury and Venus) for convenient colonization.
