| Hyperion's orbital eccentricity and highly nonspherical shape, which is unusual for a body as large as it is, have led to a complicated interaction between its spin and orbital angular momentum. |
| Another peculiarity of Hyperion is its nonspherical shape, which is sometimes described as resembling a thick hamburger patty. |
| Falling raindrops and other hydrometeors have, in general, nonspherical shapes and mean canting angles that are due to aerodynamic and gravitational forces. |
| An added neutron may also cause the nucleus to assume a nonspherical shape. |
| This same centrifugal force is responsible for the fact that the Earth is slightly nonspherical, bulging just a bit at the Equator. |
