weight = Fgravity = G * Mobject * Mplanet / Rplanet^2
where G = 6.67 * 10^-11 Newtons m^2/kg^2
For moon:
Mmoon = 7.35 * 10^22 kg
Rmoon = 1.74 * 10^6 meters
For Mars:
Mmarss = 6.42 * 10^23 kg
Rmars = 3.43 * 10^6 meters
By the way for earth
Mearth = 5.98 * 10^24 kg
Rearth= 6.38 * 10^6 meters
weight of whatever on the moon should come out around 1/6 of the weight on earth
