The weight of one designated object on a planet, moon, star, or other astronomical body is directly proportional to the astronomical body’s mass and inverse-squarely proportional to the distance from the center of the astronomical body. The square of escape velocity is directly proportional to the astronomical body’s mass and inversely proportional to the distance from the center of the astronomical body. In both cases, it is assumed that the mass of the designated object is negligible compared to the mass of the astronomical body.

It is thus possible, given a list of masses and radii, to calculate, first of all, changes in weight when moving somewhere else in the Solar System. For the following objects, multiply your Earth weight by the factor given to find your weight on the surfaces of other bodies of the Solar System.

For these statistics, influence from outer bodies is not factored in.

You won’t need to fire rockets to get off a Pallene. It’s still advised that you do, though, as otherwise you might plunge into Saturn.
