Your Age & Weight on Other Worlds

Real surface gravity ratios and orbital periods — how old and how heavy would you be there?

🪐 Age & Weight

56.7 lbs on Mars

You'd have had 16 Mars years (1.88-Earth-year orbit)

Weights use surface gravity (for Jupiter, at the cloud tops, since there is no solid surface). Ages are your Earth age divided by each world's orbital period.
