- Organizing and summarizing search results for youA sphere is based on a circle, while a spheroid (or ellipsoid) is based on an ellipse. A spheroid is a sphere flattened at the poles, and its shape is defined by two radii, the semimajor axis and the semiminor axis. If the ellipse is rotated about its minor axis, the result is an oblate spheroid, flattened like a lentil or a plain M&M. If the generating ellipse is a circle, the result is a sphere.2 Sources

Spheroid - Wikipedia
A spheroid, also known as an ellipsoid of revolution or rotational ellipsoid, is a quadric surface obtained by rotating an ellipse about one of its principal axes; in other words, an ellipsoid with two equal semi-diameters. A spheroid has circular symmetry. If the ellipse is rotated about its major axis, the result is a prolate … See more

Spheroid - Explanation, Applications, Shape, Example and FAQs
- The neutrons and protons of an atomic nucleus are mostly found in the spherical, oblate, or prolate spherical shapes along with having a spinning axis. Deformed nuclear shapes typically form as an outcome of the competition between electromagnetic repulsion between protons, quantum shell effects, and surface tension.
