Rotational flattening of planets

flattening of planets, rotational flatteningAbstract
Rotating celestial bodies do not have spherical symmetry, since the effective gravity is
different between the poles and the equator. Deviation from sphericity, dubbed the flattening
of the body, depends on the rotation velocity but also on the internal structure. In this article
the flattening of solar system planets is calculated by considering these bodies either as an
incompressible fluid or constituted by an elastic material. Comparison with data permits to
obtain information about the internal structure of these bodies.
