Summary: ellipsoid in Brief
An 'ellipsoid' [ih-lip-soid] is a three-dimensional shape that resembles a flattened sphere, with two axes of different lengths. It is commonly used to describe the shape of planets, celestial bodies, and other objects in space, as well as the human head. The term 'ellipsoid' also encompasses phrases like 'ellipsoid of revolution,' which describes an ellipsoid generated by revolving an ellipse about one of its principal axes, and 'ellipsoidal mirror,' which refers to a mirror whose reflecting surface is an ellipsoid of revolution.
