Iceman_Cometh: aerojockey: I came here to call shenanigans, but I see it's been covered.Earth is closer than 0.99 AU, outside the supposed "habitable zone", in July at least. So if the Earth were to orbit the sun at the distance it is during July for the whole year, all the water would evaporate? Sure.No it isn't. Earth is farther away from the sun in July than at any other time.
Jubeebee: simplicimus: Apparently Earth is outside the habitable zone, at the zone begins at .99 AU.That's kind of how I read this too. The earth's orbit is sufficiently elliptical that I would think we spend a good part of the year farther out than 0.99AU.I am surprised Venus isn't in the habitable zone though. I thought Venus would be a nice place if not for all of the carbon mon/dioxide and sulfuric acid in the atmosphere.
Tommy Moo: Why is liquid water necessary for life? Isn't this a paradigm? Of course a solvent medium is best for bringing together the ingredients necessary for the right chemical reactions to occur, so some form of liquid on the surface is likely necessary, but why couldn't there be an entire ecosystem that arises based on ammonia? It is a polar solvent, like water. Reactions might take longer at colder temperatures, but this would only mean that life would take a billion years to evolve to the same extent as 100 million earth years.

The My Little Pony Killer: If you really want Pluto, you can go ahead and name all the rest of the thousands of Pluto-sized objects in our solar system.
