[QUOTE="Quickleaf, post: 6877643, member: 20323"] Awesome feedback :) Thanks! My example is a 1 km diameter (500 m radius) "squashed" sphere. [MENTION=1]Morrus[/MENTION] That's exactly one of the questions I'm trying to determine. How high up do you have to climb a building for there to be noticeable change in gravity.
