This story on Reddit involves a 1 km by 1 km by 1.79 lightyear block of lead in deep space, and I was wondering if it was at all feasible (though that question is probably out of scope). To ask a more answerable question, how would I determine the surface gravity of such an object? In particular, how much gravity would you experience if you were standing in the middle of one of the two square sides?
