Spheroid
</dt>
An ellipsoid; a
figure resembling a sphere. Also called ellipsoid or ellipsoid of
revolution from the fact that it can be formed by revolving an ellipse
about one of its axes. If the shorter axis is used as the axis of revolution,
an oblate spheroid results, and if the longer axis is used, a prolate spheroid
results. The earth is approximately an oblate spheroid.
