I am curious to know if the gravitic field of a rotating, disk-shaped mass is denser along its ecliptic. I'm referring to rotating bodies such as stellar systems, galaxies, etc. I would like to know if a second mass, passing through the ecliptic, would experience a difference such as tidal forces or perturbations. Basically, does a massive disk have any difference in its gravitic pull axially vs radially? From a great distance, it would just be a point-source, but up close I'm thinking that the magnitude of the vectors of individual bodies comprising the whole would be less axially than radially.
