>>7648044>Mercury - Too hotNah, with no atmosphere to worry about, staying cool isn't that big of a challenge. Just stay in the shade and it's otherwise pretty much like living on the Moon. Much easier than trying to hang out in limbo above Venus.
The big issue with Mercury is getting there. It's not a convenient place to stop or even fly by.
>VenusYeah, but it's a much more challenging proposition than subsisting in a planet with little to no atmosphere to cause problems.
>MarsAtmosphere is thick enough for aerobraking, yet thin enough not to cause major thermal management problems. Easily the easiest place to reach and explore other than the Moon and perhaps Phobos.
>Jupiter; Saturn - Possible to survive in the same conditions as Venus, but much more difficult due to the extreme coldWon't work. Balloons wouldn't float in the atmosphere (unless heated and very, very large) of these two since it's composed of hydrogen and helium. But these planets DO have the most interesting Moons, which could be far more amenable to exploration and settlement.
>Uranus;NeptuneSame problem as Jupiter and Saturn, only the lower temperatures might make it feasible to survive in a hot gas balloon at elevated pressures. Still tremendously more difficult than any of the terrestrial planets.
>Pluto - Not a planet, but basically the same as above.With no atmosphere, it's again much like trying to live on the Moon or in space. Or more closely, on one of the Jovian moons. VERY difficult to get to, though.
