The flattening, ellipticity, or oblateness of an oblate spheroid is the relative difference between its equatorial radius a and its polar radius b: Oblate also refers to a member of the Roman Catholic religious order of the Missionary Oblates of Mary Immaculate, or in some cases to a lay or religious person who has officially associated himself (or herself) with a monastic community such as the Benedictines for reasons of personal enrichment without... The equator is an imaginary circle drawn around a planet at a distance halfway between the poles. ... ...
f = (a − b) / a
The flattening of the Earth is 1:298.25275 (which corresponds to a radius difference of 21.385 km of the Earth radius 6378.135 - 6356.75 km) and would not be realized visually from space,
whereas the flattening of Jupiter is 1:16 (which can be seen even in a small telescope, or that of Saturn ~ 1:10

Flattening of the posterior aspect of the skull in early infancy is by far the most common reason for referral of new patients to the pediatric neurosurgeon; it is more common than craniosynostosis by an order of magnitude.
Subsequent brain expansion remodels the skull and reduces the flattening somewhat, and the asymmetry that persists is mitigated further by disproportionate enlargement of the neck muscles and the facial skeleton and by hair growth.
Asymmetrical positional flattening is almost always associated with a degree of congenital torticollis, and passive range of motion exercises for the neck are useful at any age.
