Weight is dependent on both the mass of the object and the gravitational pull of a planet. This is why people weigh differently on other planets, which have a different gravitational force. Using the formula W = G(m1)(m2)/r^2 where:
W = weight or force
G = Gravitational constant (not the same as g) = 6.67x10^-11 m^2/kg^2
m1 = mass of object 1 (person)
m2 = mass of object 2 (planet)
r = radius of planet
This gives a weight of 677.26 Newtons
