From Wikipedia, the free encyclopedia

A polar bulge is a bulge that a planet or a natural satellite can have at its geographical poles, disorting it into a prolate spheroid. None of the planets in The Solar System have a polar bulge, they instead have an equatorial bulge, but it is present in some of the moons in The Solar System.
