Darker areas absorb more sunlight. Am I right to think Pluto's orbit crosses the borders of multiple sun-centred concentric zones, analagous to the habitability zone for liquid water, where many phase-space curves cluster in a fairly narrow temperature range? (Phase-spaces for what, though? Presumably the surface is covered in tholins and similar fancy hydro-carbons, with some high-albedo ices?) Hendric's post #70 above makes me wonder whether the Iapetus albedo dichotomy and the tantalising hints about Pluto could be due to a phenomena similar to "albedo flip feedback". (NB, that's a term from terrestial climatology, a banned topic, so I'm not even going to describe it: GIYF. But it seems similar to the Iapetus story.) -------------------- --
