Please type your __subject__ in the **School Subject** box. Any other words, __including obscure abbreviations__, are likely to delay responses from a teacher who knows that subject well.

radius 5x, makes Gravity 1/25th

mass= 25x, makes the graviaty 25x

so it looks like the person weights 150lbs on that planet.
