Extreme Planets from StarGenThis page lists the most extreme habitable planets from a large test run of StarGen that created more than a half million systems, 10,000 of each of the 51 stars from the SolStation list of stars. The command used to create these systems was:

My original test run included one system with three planets with breathable atmospheres, but in the latest run one of those planets became too cold to support liquid water. I made two more runs starting with -s2 and -s3. In the third run, a system with 3 planets with breathable atmospheres showed up. Where the first system had one terrestrial and two martians, this one had three terrestrials. I've included it here, even though it took a million more systems to get it than the other systems on this page.
