TNO = trans neptunian object, basically far out dwarf planet

Obviously there would be less sun to greenhouse, but theoretically could that be a way to have closer-to-earth habitats far away from a star?

edit: the TNO does not have to be like Pluto, it can be bigger or have different conditions

    Shouldn’t the greenhouse effect be trapping whatever does make it though? I thought greenhouse effects could lead to a positive feedback loop scenario

      The greenhouse effect won’t even start if the greenhouse gases are frozen on the surface

        So what if there is a temporary heat source (nuke or something) or it originated from closer to the sun?

          Intuitively I would assume that a single event would either not release enough energy to start a feedback loop or destroy the planet altogether, but I have no idea how to calculate that.

      The greenhouse effect still has a limit to how much it can trap.

      At the end of the day infrared radiation is still basically light.

      Even on the cloudiest day, or when there is super dense smoke or ash, it is still not pitch black out. Some light gets through. If you are looking into a mirror, it might seem like it reflects 100% of light. But they only reflect around 95%.

      You would require something which can let through 100% of all sunlight, but still trap 99.5% from leaving.

      You could have a look at how one-way mirrors work, to understand the percentages of light passed through and reflected.
