[Space] Making a solar system with 3 (semi-) habitable planets?

[vicky_molokh]

I ditched the near-sun planet, and just managed to put in a Terra-like Garden at 0.79 and a standard thin-atmosphere 'garden' at 1.1 au. I get the feeling that making borderline Garden/Rock and Garden/Greenhouse planets is somewhat harder than making any of the three types (takes much more careful balancing acts).

The star is currently 0.77 Luminosity.

I was forced to change temperatures of the terran planet to 13/27/43°C. A bit on the high side, but I guess that just means I have to make the polar zones almost habitable, and the equator a somewhat uncomfortable place to live (from a human PoV, anyway). (For the record: I don't quite get how to calculate zonal temperatures from those three yearly world-average temperatures.)
