A spheroid, or ellipsoid of revolution, is a quadricsurface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters.
If the ellipse is rotated about its major axis, the result is a prolate (elongated) spheroid, like an American football or rugby ball. If the ellipse is rotated about its minor axis, the result is an oblate (flattened) spheroid, like a lentil. If the generating ellipse is a circle, the result is a sphere. A spheroid has circular symmetry.
Because of the combined effects of gravity and rotation, the Earth's shape is not quite a sphere but instead is slightly flattened in the direction of its axis. For that reason, in cartography the Earth is often approximated by an oblate spheroid instead of a sphere. The current World Geodetic System model uses a spheroid whose radius is 6,378.137km at the equator and 6,356.752km at the poles.
The word spheroid originally meant an approximately spherical body, admitting irregularities even beyond the bi- or tri-axial ellipsoidal shape, and that is how it is used in some older papers on geodesy (for example, referring to truncated spherical harmonic expansions of the Earth).
Don't let anyone try to convince you that the earth is a sphere! It's actually closer to an ellipsoid. How does your airline pilot know which direction to head when he’s over the ocean with no landmarks? How do we know the exact boundaries between parcels of land and between states and countries? These are questions we answer with geodesy (sometimes known as Geodetics Engineering): the science of how we characterize the shape and size of the earth.

How does your airline pilot know which direction to head when he’s over the ocean with no landmarks? How do we know the exact boundaries between parcels of land and between states and countries? These are questions we answer with geodesy (sometimes known as Geodetics Engineering): the science of how we characterize the shape and size of the earth.
