thumb|Examples of ellipsoids with equation :
An ellipsoid is a 3D shape similar to a stretched or squashed sphere, described by a mathematical equation where three different measurements determine its size along different directions. It matters because many objects in nature and science—from planets to atomic nuclei—approximate this shape, making it useful for understanding the physical world.
