It is unlikely any of the planets in the solar system could sustain humanity or life if the Earth is lost in the next few centuries. Thousands, at most, would live on the planet. We've always had an ecosystem to rely on, and even a severely damaged one would be more survivable than the cold wastes of Mars.

Or out in the middle of the Kalahari Desert, or in the center of Australia, likewise. Southern hemisphere is recommended, anyway, as probably few nukes will target there; maybe none!
