WebMar 24, 2024 · An oblate spheroid is a surface of revolution obtained by rotating an ellipse about its minor axis (Hilbert and Cohn-Vossen 1999, p. 10). To first approximation, the shape assumed by a rotating fluid (including the Earth, which is "fluid" over astronomical time scales) is an oblate spheroid.

WebJul 10, 2024 · While ellipsoids are round and smooth like spheres, they are not symmetrical when divided in all directions. Because the circumference of the Earth’s equator is about 42mi (67km) longer than its meridians, the planet cannot be described as a perfect sphere. Scientists have developed several ellipsoidal models of the Earth over the years.
