In 1687 Isaac Newton published the Principia. He included a proof that a rotating self-gravitating fluid body in equilibrium takes the form of an oblate ellipsoid of revolution (a spheroid). The amount of flattening depends on the density and the balance of gravitational force and centrifugal force.
Who discovered oblate spheroid?
Isaac Newton first proposed that Earth was not perfectly round. Instead, he suggested it was an oblate spheroid—a sphere that is squashed at its poles and swollen at the equator.
How did Earth become an oblate spheroid?
The Earth is not a perfect sphere. Because it is spinning, it "bulges" at the middle. This makes the Earth a "squished sphere," or "oblate spheroid."
