Question about Mollweide

[Baleia espacial]

What was used to calculate the shape and gravity of the planet Mollweide?

I didn't calculate the shape, but the gravity is fairly straightforward; you take the mass and calculate the gravity at the radius corresponding to your latitiude, then subtract the value of centrifugal force at that latitude. The easy cases are the gravity at the equator and the gravity at the poles.
