if based ONLY on weight and gravity as a factor, every planet and moon in our solar system could be landed on and walked on by man, except for Jupiter. Of course there are other considerations, but it's true; if a comfort zone could be maintained around a human regarding temperature, breathable air, pressure, then personal weight due to gravity would not preclude us being on almost all the heavenly bodies in our solar system.
