Let's say someone who was conceived and born in microgravity and spent his/her entire life on a space station in weightlessness until age 20 decides to land on a celestial body. How much surface gravity would such a celestial body have to have for the human to get accustomed to it? Such a human obviously cannot land on any of the four inner planets where he/she would probably die instantly since his/her bones would break. However the human still has some strength because he/she might have moved more massive things sometimes, for instance.
What if such a person would try to land on Lutetia in 0.003g or Ceres in 0.029g or Pluto in 0.063g? What would happen to him/her?
